Hello,
I have an issue on IE9 and IE10 (does NOT occur on firefox and chrome) where the text of a4j:commandButtons in a rich:popupPanel is not rendered after showing the popup until a mouse over on the button occurs.  I've found it very hard to pinpoint the conditions when this will occur but I can say the following:
 
-> If I remove the CONTENT from <f:facet name="header"></f:facet> the problem disappears.
-> If I INCLUDE a rich:extendedDataTable in the popup the problem disappears (and I can put whatever I want in the <f:facet name="header"></f:facet> tags).
I am using RichFaces 4.3.0, Apache MyFaces 2.1.10 running on a tomcat 6 server.
 
This problem is driving me crazy, any help is appreciated.
 
Screenshot of the problem (a mouse over shows the text):
 

 
After a mouse over:
 

 
The page source of my dialogue (cut down to it's most simplistic with the render issue occurring):
  
<rich:popupPanel modal="true" id="${id}" resizeable="false"
  moveable="true" show="false" height="250" width="300">
  <f:facet name="header">
   
   <!-- REMOVING THIS PANEL GROUP FIXES THE PROBLEM!!! -->
   <h:panelGroup id="${id}pg21">
    <h:panelGroup id="${id}pg22" style="text-align : left">
     <h:graphicImage id="${id}gi24"
      value="#{initParam.farmconnectImagesDir}/edit-contact-details-16.png" />
     <h:outputText id="${id}ot26" value="${messages.setPoint}" />
    </h:panelGroup>
   </h:panelGroup>
  </f:facet>
  <h:form id="${id}dialogueForm">
        
   <a4j:commandButton id="submitCommandButton"
         value="Submit" >
    </a4j:commandButton>
   </h:form>
 </rich:popupPanel>
 
 
 
Thanks for any feedback.
