When a jPDL pageflow definition is in place, Seam switches to a particular conversation by restoring the current jBPM process state. This is a more flexible model, since it allows the same view-id to have different descriptions depending on the current <page> node. The description text is defined by the <page> node:
<pageflow-definition name="shopping">
<start-state name="start">
<transition to="browse"/>
</start-state>
<page name="browse" view-id="/browse.xhtml">
<description>DVD Search: #{search.searchPattern}</description>
<transition to="browse"/>
<transition name="checkout" to="checkout"/>
</page>
<page name="checkout" view-id="/checkout.xhtml">
<description>Purchase: $#{cart.total}</description>
<transition to="checkout"/>
<transition name="complete" to="complete"/>
</page>
<page name="complete" view-id="/complete.xhtml">
<end-conversation />
</page>
</pageflow-definition>
<pageflow-definition name="shopping">
<start-state name="start">
<transition to="browse"/>
</start-state>
<page name="browse" view-id="/browse.xhtml">
<description>DVD Search: #{search.searchPattern}</description>
<transition to="browse"/>
<transition name="checkout" to="checkout"/>
</page>
<page name="checkout" view-id="/checkout.xhtml">
<description>Purchase: $#{cart.total}</description>
<transition to="checkout"/>
<transition name="complete" to="complete"/>
</page>
<page name="complete" view-id="/complete.xhtml">
<end-conversation />
</page>
</pageflow-definition>
