    meaning/reason of (a4j:log) 'class  java.lang.RuntimeException' / 'object not found: 0'

    Axel Roeber Newbie



      I have some difficulties to (re)render a rich:popupPanel. I added <a4j:log> to get an idea what could be the reason. I assume that the problem is independend of the popup component. But the aj4:commandLink seems to raise an error. Even if all actions were remoded, there is still this error in the a4j:log panel. This is only a small part of a complex page but everything else seems to work fine.


      <rich:dataTable value="#{...}" var="prj">




      <a4j:commandLink  value="#{prj.name}" title="..."  />



      Clicking on one of the links in the table the following output is shown in the aj4:log panel:


      debug[12:20:13.878]: New request added to queue. Queue requestGroupingId changed to j_idt66:0:j_idt343:j_idt78

      debug[12:20:13.880]: Queue will wait 0ms before submit

      debug[12:20:15.081]: richfaces.queue: ajax submit successfull

      debug[12:20:15.082]: richfaces.queue: Nothing to submit


      Any idea what could be the reason or how to get more information to analyze the problem?
