8.12.3. RichFaces (Ajax4jsf)

RichFaces (Ajax4jsf) is the most common AJAX library used with Seam, and provides all of the controls discussed in the previous section.

eventsQueue: Provides a queue in which events are placed. All events are queued, and requests are sent to the server serially. This is useful if the request to the server can take some time to execute (for example, in heavy computation, retrieving information from a slow source) since it prevents server flooding.
ignoreDupResponses: Ignores the response produced by a request if a more recent "similar" request is already queued. ignoreDupResponses="true" does not cancel the processing of the request on the server side; it only prevents unnecessary updates on the client side.
With Seam conversations, this option should be used with care, since it allows multiple concurrent requests.
requestDelay: Defines the time in milliseconds that the request will remain on the queue. If, at this time, the request has not been processed, the request will either be sent (regardless of whether a response has been received), or discarded (if there is a more recent "similar" event queued).
With Seam conversations, this option should be used with care, as it allows multiple concurrent requests. The delay that you set (in combination with the concurrent request timeout) must be longer than the action will take to execute.
<a:poll reRender="total" interval="1000" />: Polls the server and rerenders an area, as required.
