a4j:poll only fires onces with RF 3.2.0

[cdollar393]

I've been using RF 3.1.x for quite some time and today am testing an update to 3.2.0. My project makes use of a number of a4j:push and a4j:pull to keep track of session data and warn a user of a session that is about to expire. This has worked fine with RF 3.1.4, but with 3.2.0 it seems that my a4j:poll fires one time, and then stops.

Here is the poll:

<!-- poll every 60sec -->
<a4j:poll id="poll" interval="60000" enabled="true" limitToList="true"
 reRender="dashboard, updateStamp" action="#{user.updateStats}"/>

I can see where the updateStats() method is called after the first 60sec, but not again afterwards. I've changed the interval, but that hasn't helped.

Checking the ajax log I see:

Anyone have an idea as to what the problem might be?

Thanks!

More info...

Removing the attribute

limitToList="true"

gets it working and firing repeatedly. This seems like a bug to me? mabye I should open a jira issue?

Also, I'm not able to get a4j:push to work with 3.2.0. Events are fired like normal, but it appears that the push doesn't get them as nothing is ever reRendered. To test it further I added an

oncomplete="alert('foo');"

to the a4j:push tag, and I never see it either.

Has anyone else encountered this?

So I'm pretty sure the reason a4j:push isn't working for me is related to this bug http://jira.jboss.com/jira/browse/RF-2960 since I too am using facelets.

Is anyone else seeing the problem with limitToList in an a4j:poll ?? I'm happy to open a jira issue for this, but I would like to know if anyone else is seeing the same behavior before doing so.

a4j:poll is designed to update itself in order to be sensitive for attributes (such enable, oncomplete) changes.
As soon as you limit update to the list, but not include the a4j:poll to this list, it is fired just once.

So, it works like designed. Just add "poll" to the reRender.

I tried to use a4j:poll to periodically refresh some datatable.
It works correctly until I go to another page of the application and return to the screen with a4j:poll, the following error occurs js:

Message: Object required
Linha: 2797
Caractere: 1
Código: 0
URI: http://localhost:8080/SysTest/a4j/g/3_3_3.Final/org/ajax4jsf/framework.pack.js.jsf

Someone has been there, have any solutions?

Thanks.

My code:

<a4j:region>
  <h:form>
    <a4j:poll id="poll" interval="5000" timeout="50000" action="#{myMB.findConfig}" reRender="poll,gridS"/>  
  </h:form>
</a4j:region>

 
<h:form>
   <rich:dataGrid value="#{myMB.listConfig}" id="gridS"  var="sen" columns="3" elements="9" width="100%">
      <rich:panel bodyClass="pbody">
         <f:facet name="header">

I tried to open http://livedemo.exadel.com/richfaces-demo/richfaces/poll.jsf then navigated to other component and returned back. All works fine for me. Maybe you trying to use navigation via Ajax? If so make sure it's redirect. If not helps try to replace navigation control with h:command.
