    Seam 2.0.0.BETA1 & Ajax4JSF 1.1.1 problem (bug?)

    Kenneth Christensen Novice

      I really don't know if this problem is a JBoss Seam or/and JBoss Ajax4JSF or/and JBoss EL issue !

      But what I do know, this problem occur only when I'm using JBoss Seam 2.0.0.BETA1 and JBoss Ajax4JSF 1.1.1.
      Works fine with JBoss Seam 1.2.1.GA and JBoss Ajax4JSF 1.1.0.

      Environment:

      JBoss AS 4.2.0.GA
      JBoss Seam 2.0.0.BETA1
      JBoss Ajax4JSF 1.1.1
      Facelets 1.1.11

      Okay, now to the problem :-)

      I have a <h:selectOneMenu> with a <a4j:support>:

       <h:selectOneMenu id="foodCategory" style="margin-left:5px" value="#{foodBean.category}">
       <f:selectItem itemValue="*" itemLabel="#{messages.foodItemGroup00}"/>
       <f:selectItems value="#{foodProductUi.categories}"/>
       <a4j:support event="onchange" ajaxSingle="true"/>
       </h:selectOneMenu>
      


      and a <h:dataTable> (BTW: this is an example - really simple one for this thread):

       <h:dataTable var="componentName" value="#{foodDomain.componentBasicTypeNames}">
       <h:column>
       <h:outputText rendered="#{foodDomain.componentsAsMap[componentName].type.mandatory}"
       value="#{foodDomain.componentsAsMap[componentName].name}" escape="false"/>
       </h:column>
       </h:dataTable>
      


      In one JSF file.

      An exception is thrown when I select another item from the <h:selectOneMenu> and it looks like the dataTable variable 'componentName' is null
      when Ajax4JSF is re-evaluating/re-building the JSF page (BTW: I really don't understand why Ajax4JSF need to re-evaluate/re-build the whole page and not only the <h:selectOneMenu> - I'm using a ajaxSingle="true").

      Stacktrace:
