rowSelection="single">
<f:facet name="nodeStamp">
<af:group id="g1">
<af:image source="/image/#{node.treeLevel}.jpg" id="i1"
inlineStyle="width:16px; height:16px; vertical-align:middle;"/>
<af:outputText id="ddl" value="#{node.name}">
<af:showPopupBehavior popupId="myPopup" triggerType="contextMenu"/>
</af:outputText>
</af:group>
</f:facet>
<f:facet name="contextMenu">
<af:popup id="myPopup" popupFetchListener="#{treeTest.popupListener}"
contentDelivery="lazyUncached">
<af:switcher id="s1" facetName="#{treeTest.level}">
<f:facet name="1">
<af:menu text="menu 1" id="m1">
<af:forEach items="#{treeTest.menuItems['0']}" var="menuItemss">
<af:commandMenuItem text="#{menuItemss.name}"
actionListener="#{bindings.onNodeClicked.execute}"
disabled="#{!bindings.onNodeClicked.enabled}">
</af:commandMenuItem>
</af:forEach>
</af:menu>
</f:facet>
<f:facet name="2">
<af:menu text="menu 2" id="menu1">
<af:forEach items="#{treeTest.menuItems['1']}" var="menuItemss">
<af:commandMenuItem text="#{menuItemss.name}"
actionListener="#{bindings.onNodeClicked.execute}"
disabled="#{!bindings.onNodeClicked.enabled}">
</af:commandMenuItem>
</af:forEach>
</af:menu>
</f:facet>
</af:switcher>
</af:popup>
</f:facet>
</af:tree>
========================================================
I want to get the commandMenuItem tag's information, i use following code in onNodeClicked method try to get it,
FacesContext facesContext =FacesContext.getCurrentInstance();
ELContext elContext = facesContext.getELContext();
ExpressionFactory expressionFactory =facesContext.getApplication().getExpressionFactory();
ValueExpression exp =expressionFactory.createValueExpression(elContext,"#{menuItemss.name}", Object.class);
but the exp is null.
Please help me to solve this problem.
Thank you very much.

You might need a #
ValueExpression exp =expressionFactory.createValueExpression(elContext,"#{menuItemss.name}", Object.class);
