[jboss-user] [JBoss Seam] - Seam 2.0.0.BETA1 & Ajax4JSF 1.1.1 problem (bug?)

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").
