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:
