Hi Kike,

Yes I tried actionListener and action both with a4j support. No action is getting performed. But at the same time, if I load the rich combo box directly(without radio button action), a4j is working

I tried with all possible events like onchange and onselect

<rich:column style="align:center">
        <h:panelGroup id="dynamicComponentGroups" style="border: 0px">
         <h:panelGrid style="text-align:center;border: 0px">
          <rich:comboBox id="componentGroupname"
          value="#{componentMapping.selectedCompGroupName}"
          defaultLabel="Select ComponentGroup">
          <f:selectItems value="#{componentMapping.componentGroupNames}" />
          <a4j:support event="onchange"
           action="#{componentMapping.fetchGroupNames}"
           BypassUpdates="false" reRender="componentGroupValue"
           id="comboAjax" status="waitStatusadmin">
          </a4j:support>
         </rich:comboBox>

         </h:panelGrid>
        </h:panelGroup>
       </rich:column>

hi ,

I need to rerender here so a4j support is must for me.

Posting my full code here...If I remove radio button code here and load rest of the components by default a4j support is working here.

I have been struggling since last 10 days with this problem. Could anybody look into this and let me know what exactly  I m doing wrong here.
