    strange problem with ajax4jsf and s:selectItems

    Hannes Schulz Newbie

      Hi,

      i'm getting a exception on my page and i have no clue why. the overall architecture is a little bit hard to explain so i'll try to do it in short and if you need more details please tell me.

      I have have a few input fields within a a4j:region tag. if the value of a field changes all data is submitted to the bean and if the validation succeeds an object is created and added to a list. the list is in return outjected as datamodel and the table displaying the list is rerendered and the region of the input fields.

      <a4j:region>
       <h:panelGrid id="allocateArea" columns="2" columnClasses="label,input">
       <h:outputLabel for="utilisationType" value="#{messages.utilisationType}:"/>
       <h:panelGroup>
       <h:selectOneMenu
       converter="#{objectmanager.modeOfUtilisationConverter}"
       id="utilisationType"
       value="#{tcmanager.modeOfUtilisation}">
       <f:selectItem itemLabel="" itemValue="#{objectmanager.nullModeOfUtilisation}" />
       <s:selectItems value="#{tcmanager.modesOfUtilisation}"/>
       <a4j:support event="onchange" reRender="addArea" limitToList="true" ajaxSingle="true"/>
       </h:selectOneMenu>
       </h:panelGroup>
       <h:outputLabel for="allocatedAreas_numOfAreas" value="#{messages.amount}:"/>
       <h:panelGroup>
       <h:inputText
       id="allocatedAreas_numOfAreas"
       value="#{tcmanager.numOfAreas}">
       <a4j:support event="onkeyup" requestDelay="50" reRender="addArea,errorPanel_allocatedAreas" limitToList="true"/>
       </h:inputText>
      
      ... more input fields
      </a4g:region>


      so, whenever something changes all data is submitted. from time to time i get an exception when i add table items:
