RichFaces, Regions and Jboss EL - bad mix?

[emsa]

I don't know if this is RichFaces, Seam or EL issue or if this is just impossible (original problem JBoss  ELExpression Evaluates To Null)

This does not work, id is always null is action method:

<rich:dataTable   
  value="#{admin.infoEditList.items}" 
  var="info">
    <h:column>
        <a4j:region>
            <a4j:commandLink 
              action="#{admin.infoEditList.selectItem(info.id)}" />                            
        </a4j:region>
    </h:column>
</rich:dataTable>

removing the region and the correct id is used in the action:

<rich:dataTable   
  value="#{admin.infoEditList.items}" 
  var="info">
    <h:column>
        <a4j:commandLink 
              action="#{admin.infoEditList.selectItem(info.id)}" />                            
    </h:column>
</rich:dataTable>

placing the region outside the table works as well:

<a4j:region>
  <rich:dataTable   
   value="#{admin.infoEditList.items}" 
   var="info">
     <h:column>
         <a4j:commandLink 
               action="#{admin.infoEditList.selectItem(info.id)}" />                            
     </h:column>
 </rich:dataTable>
</a4j:region>

replacing the a4j:commandLink with h:commandLink or s:link makes no differance - the EL is not evaluated at render time.
