    <s:convertEntity> with ajax support

    asaf sh Expert

      Hey,

      I get a NPE when trying to combine selectItems+convertEntity+a4j support,


      I have the following code (with facelets)

      <h:selectOneMenu id="someId" value="#{myEjb.sb1}" required="false">
      <s:selectItems value="#{someList.resultList}" var="ia" label="#{ia.name}" noSelectionLabel="Any"/>
      <s:convertEntity/>
      <a:support event="onchange" action="#{myManager.valueChanged}" ajaxSingle="true" reRender="actionsPanel" />
      </h:selectOneMenu>
      



      Of course I have the action in myManager and 'someList' is an EJBql defined in components.xml file.

      When modifying the selectbox options I get the following exception:
