Red Hat Decision Manager 7.11

Abstract

This document contains release notes for Red Hat Decision Manager 7.11.

Preface

These release notes list new features, features in technology preview, known issues, and issues fixed in Red Hat Decision Manager 7.11.

Making open source more inclusive

Red Hat is committed to replacing problematic language in our code, documentation, and web properties. We are beginning with these four terms: master, slave, blacklist, and whitelist. Because of the enormity of this endeavor, these changes will be implemented gradually over several upcoming releases. For more details, see our CTO Chris Wright’s message.

Chapter 1. Product overview

Red Hat Decision Manager is an open-source decision management platform that combines business rules management, complex event processing, Decision Model & Notation (DMN) execution, and Red Hat build of OptaPlanner for solving planning problems. It automates business decisions and makes that logic available to the entire business.

Business assets such as rules, decision tables, and DMN models are stored in a central repository. This ensures consistency, transparency, and the ability to audit across the business. Business users can modify business logic without requiring assistance from IT personnel.

Red Hat Decision Manager 7.11 provides increased stability, several fixed issues, and new features.

Red Hat Decision Manager is fully supported on Red Hat OpenShift Container Platform and can be installed on various platforms.

Note

Red Hat Decision Manager requires Java 11 or later.

For information about the support policy for Red Hat Decision Manager, see the Release maintenance plan for Red Hat Decision Manager 7.x and Red Hat Process Automation Manager 7.x.

Chapter 3. New features

This section highlights new features in Red Hat Decision Manager 7.11.

3.1. Business Central

3.1.1. Ability to sort the column values in a guided decision table

In guided decision tables, you can now double-click a column name to sort the values in ascending order, and if you double-click on the same column, the values are sorted in descending order. For more information, see Designing a decision service using guided decision tables.

3.1.2. Prometheus and Kafka data set provider

In Business Central, it is now possible to use the Prometheus and Kafka data set provider to create a data set to fetch the data from an external data source and use that data for the reporting and external components.

The following list provides a summary of the two new data set providers in Business Central:

  • You can use the Prometheus data set provider which generates a data set using the Prometheus query.
  • You can use the Kafka data set provider which generates a data set using metrics from Kafka broker, consumer, or producer.

For more information, see Configuring Business Central settings and properties.

3.1.3. Test scenarios

The test scenarios designer in Business Central is now available with the new features supported in Red Hat Decision Manager 7.11.

  • The test scenarios designer in Business Central now supports the nested enumeration data type attributes in rule-based test scenarios.

  • In the test scenarios designer, you can now see the actual test results instead of a generic message in a list or a map collection editor. It is now possible to monitor the following information in a collection editor:

    • The wrong value
    • The path to reach out to the wrong value
    • The correct value

For more information, see Testing a decision service using test scenarios.

3.2. KIE Server

3.2.1. PMML trusty implementation

You can now use PMML trusty implementation to embed a PMML call in a Java application or to execute a PMML model using KIE Server. For more information about PMML trusty implementation, see Designing a decision service using PMML models.

3.2.2. REST endpoints for specific DMN models

Red Hat Decision Manager now provides model-specific DMN KIE Server endpoints that you can use to interact with your specific DMN model directly over REST, without using the KIE Server Client (Java) API. The following REST endpoints of the KIE Server are automatically generated based on the content of the DMN model:

  • POST /server/containers/{containerId}/dmn/models/{modelname}: A business-domain endpoint for evaluating a specified DMN model in a container
  • POST /server/containers/{containerId}/dmn/models/{modelname}/{decisionServiceName}: A business-domain endpoint for evaluating a specified decision service component in a specific DMN model available in a container
  • POST /server/containers/{containerId}/dmn/models/{modelname}/dmnresult: An endpoint for evaluating a specified DMN model containing customized body payload and returning a DMNResult response, including business-domain context, helper messages, and helper decision pointers
  • POST /server/containers/{containerId}/dmn/models/{modelname}/{decisionServiceName}/dmnresult: An endpoint for evaluating a specified decision service component in a specific DMN model and returning a DMN Result response, including the business-domain context, helper messages, and help decision pointers for the decision service
  • GET /server/containers/{containerId}/dmn/models/{modelname}: An endpoint for returning standard DMN XML without decision logic and containing the inputs and decisions of the specified DMN model
  • GET /server/containers/{containerId}/dmn/openapi.json (|.yaml): An endpoint for retrieving Swagger or OAS for the DMN models in a specified container

For more information about model-specific DMN KIE Server endpoints, see Designing a decision service using DMN models and Interacting with Red Hat Decision Manager using KIE APIs.

3.3. DMN Designer

3.3.1. Enhanced suggestions for DMN literal boxed expressions

You can now see more suitable suggestions for literal boxed expressions in Business Central. When you enter a FEEL expression in the editor, the first suggestions that appear are based on the return type of FEEL functions and inferred type of the context.

3.4. Red Hat build of OptaPlanner

3.4.1. OptaPlanner 8

  • Red Hat Decision Manager includes OptaPlanner 8 as well as OptaPlanner 7. OptaPlanner 7 is now deprecated and might be removed in a future release. For information about migrating your projects from a previous version of OptaPlanner, see Upgrading your Red Hat build of OptaPlanner projects to OptaPlanner 8.
  • OptaPlanner has added a school timetable and vaccination appointment scheduler quick start for Red Hat build of Quarkus. For more information, see Red Hat build of OptaPlanner quick start guides.
  • The employee rostering and vehicle route planning starter applications have been migrated to the Red Hat build of Quarkus.
  • The dinner party example has been removed.
  • The Constraint Streams API is now richer, faster, and more stable and provides better error messages.
  • ScoreManager now supports score explanations.
  • The SolverManager API now provides the ability to listen to both the best solution events and the solving ended event.
  • OptaPlanner is supported on-premise and on Red Hat OpenShift Container Platform 4.x (embedded) with JDK 11 only.

3.5. Smart Router

You can configure Smart Router (KIE Server Router) for Transport Layer Security (TLS) support to allow HTTPS traffic. In addition, you can disable insecure HTTP connections to Smart Router. For more information, see the "Configuring Smart Router for TLS Support" section in Installing and configuring Red Hat Decision Manager in a Red Hat JBoss EAP clustered environment

3.6. Spring Boot

3.6.1. Deployment of Red Hat Decision Manager Spring Boot business applications on Red Hat OpenShift Container Platform

Documentation about deploying Red Hat Decision Manager Spring Boot business applications on Red Hat OpenShift Container Platform is now provided. For more information see, Creating Red Hat Decision Manager business applications with Spring Boot.

3.6.2. Integration with Spring Boot version 2.3.4

Red Hat Decision Manager now integrates with Spring Boot version 2.3.4.

For more information about integrating Red Hat Decision Manager with Spring Boot, see Creating Red Hat Decision Manager business applications with Spring Boot.

3.7. The BatchExecutionHelperProviderImpl.newXStreamMarshaller() method creates a secure XStream instance

It is now possible that the the BatchExecutionHelperProviderImpl.newXStreamMarshaller() method creates a secure XStream instance. The XStream instance accepts only pre-defined KIE classes in payloads by default. If you use the XStream instance created by the method, you must add allowed classes. For example, add domain model classes in your application code or you receive the ForbiddenClassException exception.

Example code to add allowed classes

final BatchExecutionHelperProviderImpl batchExecutionHelperProvider = new BatchExecutionHelperProviderImpl();
XStream xstream = batchExecutionHelperProvider.newXStreamMarshaller();
String[] allowList = new String[]{
    "org.example.model.Person",
    "org.example.model.Company"
};
xstream.addPermission( new WildcardTypePermission( allowList ) );

Chapter 7. Known issues in Red Hat Decision Manager 7.11.0

This section lists known issues with Red Hat Decision Manager 7.11.

7.1. Business Central

The Business Central web application continues to poll in an open browser after the server has stopped [RHPAM-3635]

Issue: When you keep the Business Central web application open in a browser window, after the KIE Server has stopped, it keeps on polling the endpoint of the previously running KIE Server.

Workaround: None.

In standalone editors, the setContent method implementation must receive path and content [RHPAM-3629]

Issue: In standalone editors, the setContent implementation must implement the setContent method defined in EditorAPI along with path and content parameters instead of content only.

Workaround: None.

When an executing model uses an imported inputs and decision nodes, you receive an error message [RHDM-1733]

Issue: The test scenario tool is unable to execute any models that use imported inputs and decisions nodes. The automatically generated decision table columns reflects the incorrect values.

Workaround: None.

Method calls do not support template keys [RHDM-1729]

Issue: If you remove one of the action calls from the Business Rule Language (BRL) action column, the generated DRL file is updated incorrectly.

Steps to reproduce:

  1. Import the Mortgages sample project.
  2. Replace the original content of LoanApplication with the [LoanApplication.java].
  3. Replace the original content of Pricing Loans with the Pricing loans (1).gdst file. (This file is attached in the [RHDM-1729] issue).
  4. Validate Pricing loans (1).gdst file.
  5. Go to the Columns tab and select Action columns.
  6. For the call functions option, click Edit.
  7. Remove Call [application.addExplanation] and Call [application.deadline] and click Finish.

Workaround: None.

The Business Rule Language (BRL) columns do not support the conversion of method call data types [RHDM-1696]

Issue: When a guided decision table is converted into an XLS decision table, the method calls with String or Date data type arguments are not converted correctly.

Steps to reproduce:

  1. Import the Mortgages sample project.
  2. Replace the original content of LoanApplication with the [LoanApplication.java].
  3. Replace the original content of Pricing Loans with the Pricing loans (1).gdst file. (This file is attached in the [RHDM-1696] issue).
  4. Convert the Pricing Loans into an XLS table.

  5. Open the converted XLS table and switch to the Source tab.

    The addExplanation method assumes exp is a variable instead of constant. The deadline method assumes 08-Mar-2021 is a date, but it is a string. Some wrapper modules are needed for converting String into Date.

Expected result: Validation of the XLS table succeeds.

Actual result: Validation of the XLS table fails.

Workaround: None.

The guided decision table sorting functionality does not work in the decision table graph [RHDM-1664]

Issue: The guided decision table sorting functionality does not work in the decision table graph. The merged view of the table is not sorted correctly.

Steps to reproduce:

  1. Import the Mortgages sample project.
  2. Import the second small table.gds file attached in the [RHDM-1664] issue.
  3. Create a decision table graph that contains the Pricing Loans column with the second small table.gds file.
  4. Try to sort the second small table.

Expected result: The guided decision table sorting functionality works correctly in the decision table graph.

Actual result: The guided decision table sorting functionality does not work correctly.

Workaround: None.

The guided decision table merged view throws an error [RHDM-1663]

Issue: The merged view of the guided decision table is not sorted properly. You receive an unexpected system error.

Workaround: None.

In the guided decision table, sorting functionality does not work for LocalDate attribute [RHDM-1662]

Issue: In the guided decision table, sorting functionality does not work for LocalDate attribute.

Workaround: None.

7.2. DMN designer

Unable to create a new .scesim file in a VSCode instance when a workspace contains multiple folders [RHPAM-3621]

Issue: When there are multiple folders within one workspace, the scenario simulation editor fails when creating a new scenario for a specific DMN model.

Steps to reproduce:

  1. Create a VSCode workspace with a single folder in it.
  2. Create a valid DMN file.
  3. Create a .scesim file for the newly created DMN file.
  4. Add a new folder in a VSCode workspace.
  5. Create a different .scesim file for the same DMN file.

Workaround: Keep a single folder inside your workspace. If you want to work on multiple projects, open the projects in separate VSCode instances.

A decision service is missing the encapsulatedDecisions element for transitive dependencies in a model with multiple decision requirements diagrams [RHDM-1732]

Issue: When a model contains multiple decision requirements diagrams (DRD) and tries to reuse a decision component by adding it into a decision service node, the resulting decision service node does not contain any encapsulatedDecisions definitions for its transitive dependencies.

Steps to reproduce:

  1. Define multiple DRDs.
  2. In one DRD, define some decisions with transitive dependency on a decision.
  3. In another DRD, define decision services and reuse the previously created decision component. Do not duplicate the transitive dependency.
  4. Build and deploy your project.

  5. Complete any of the following tasks:

    • Evaluate the decision to verify the error reported in the description.
    • Check the dmn source code and determine whether or not the inputData attribute from the decision service is missing.
    • Check the decision service details in the Properties panel.

Workaround: The transitive decisions must be part of the encapsulatedDecisions section of the modeled decision service.

DMN editor removes the edges for duplicate decision nodes on canvas [RHDM-1714]

Issue: An issue occurs with the edges, when you duplicate a decision component in a canvas. The edges that are originally modeled are either shifted or removed.

Steps to reproduce:

  1. Create two decision nodes, A and B, and link them.
  2. Drag the decision node A from the Decision Components panel on canvas.
  3. Create an input node and link it to the duplicated decision node A.
  4. Click Save.

  5. Reopen the project.

    The link from the input node is now connected to the original decision node A, while the duplicated decision node has no links at all.

Workaround: Keep a single occurrence of the decision component for each DRD.

In the DMN editor, the suggestion box does not parse the function arguments [RHDM-1661]

Issue: The the DMN editor does not parse any helpful suggestions when you are writing literal expressions.

Steps to reproduce:

Expected result: The DMN editor provides helpful suggestions when you are writing literal expressions.

Actual result: The DMN editor does not parse any helpful suggestions when you are writing literal expressions.

Workaround: None.

In the DMN editor, the suggestion box parses the results of an addition expression as a list instead of a number [RHDM-1660]

Issue: When you parse an addition expression to a literal expression, the DMN editor suggests functions that return list instead of a number.

Steps to reproduce:

  1. Open a DMN editor.
  2. Add a decision node.
  3. Set the expression as Literal expression.
  4. Enter the sum([1]) + sum([2]) expression and check the suggestion box.

Expected result: The DMN editor suggests correct functions for an addition expression.

Actual result: The DMN editor suggests functions that return list instead of a number.

Workaround: None.

In the DMN editor, the suggestion box fails to recognize variables [RHDM-1658]

Issue: When you parse the number type to a literal expressions, the DMN editor fails to recognize variables.

Steps to reproduce:

  1. Open a DMN editor.
  2. Add a decision node.
  3. Set the expression as Literal expression.
  4. Enter the numeric variable + expression and check the suggestion box.

Expected result: The DMN editor recognizes variables when you parse the number type to a literal expressions.

Actual result: The DMN editor fails to recognize variables.

Workaround: None.

In the DMN editor, the suggestion box fails to recognize the duration expression [RHDM-1656]

Issue: When you try to parse the duration expression, the DMN editor suggests string functions instead of duration functions.

Steps to reproduce:

  1. Open a DMN editor.
  2. Add a decision node.
  3. Set the expression as a Literal expression.
  4. Enter the date( "2012-12-25" ) - date( "2012-12-24" ) expression and check the suggestion box.

Expected result: The DMN editor recognizes the duration expression.

Actual result: The DMN editor fails to recognize the duration expression and suggests string functions.

Workaround: None.

In the DMN editor, the suggestion box fails to recognize date expressions [RHDM-1654]

Issue: When you try to parse a date expression, the DMN editor suggests string functions instead of date functions.

Steps to reproduce:

  1. Open a DMN editor.
  2. Add a decision node.
  3. Set the expression as Literal expression.
  4. Enter the date(date and time( "2012-12-25T11:00:00Z" )) expression and check the suggestion box.

Expected result: The DMN editor recognizes the date expressions.

Actual result: The DMN editor fails to recognize the date expression and suggests string functions instead of date functions.

Workaround: None.

In the DMN editor, the suggestion box fails to recognize a negated boolean expression [RHDM-1652]

Issue: When you try to parse a negated boolean expression, the DMN editor offers different suggestions which are not related to the expression.

Steps to reproduce:

  1. Open a DMN editor.
  2. Add a decision node.
  3. Set the expression as Literal expression.
  4. Enter a false or not false expression and check the suggestion box.

Expected result: The DMN editor offers related suggestions when you parse a negated boolean expression.

Actual result: The DMN editor fails to provide related suggestions when you parse a negated boolean expression.

Workaround: None.

7.3. Red Hat build of Kogito

From given asset, wrong archetype is used to generate project [RHPAM-3654]

Issue: When you upload an asset as a source for KogitoBuild, the Red Hat build of Kogito S2I image generates the project using kogito-quarkus-archetype:1.5.1-SNAPSHOT. It is expected to use the kogito-quarkus-dm-archetype:1.5.0.redhat-00001.

Steps to reproduce:

  1. Install the RHPAM Kogito Operator.

  2. Create a KogitoBuild as follows: 

    apiVersion: rhpam.kiegroup.org/v1
