Hi,
I realy need help.
i have change the ' #{ node.selection }' expression in
<t:selectOneMenu value=" #{ node.selection }">
by a session bean ' #{ dummyNode.selection }'.
I do that because I believed that JSF can't found the variable
"node" after the submission of the form.
But the error message still happen :
Parsed Expression of unsupported type for this operation. Expression class:
org.apache.commons.el.ExpressionString. Expression: ' #{ dummyNode.selection
}'
I realy don't know what to do.
Any help will be very appreciated.
Many thanks,
Igor

Objet : dynamic form problem
Hi,
I have a many form included in a t:tree2 :
<t:tree2 imageLocation="/images" id="ProdTree" value="#{Builder.tree}"
var="node"
varNodeToggler="t"
showLines="true"
showRootNode="false"
showNav="false"
clientSideToggle="false"
>
<f:facet name="ensemble">
<h:panelGroup>
<h:outputText value="#{node.description}"/>
<f:verbatim><br/></f:verbatim>
<h:form>
<h:panelGroup
rendered="#{node.isRendered }">
<t:selectOneMenu value=" #{
node.selection }">
<f:selectItems value="#{
node.selectItemListe }" />
<f:convertNumber/>
</t:selectOneMenu>
<h:commandLink action="#{
node.action }" >
<h:outputText
value="+Add+"/>
</h:commandLink>
</h:panelGroup>
</h:form>
</h:panelGroup>
</f:facet>
<f:facet other facet ../>
</t:tree2>
Well, when "add" link is click node.setSelection() is never call. Nor
node.action().
If I remove the <form> tag setSelection is call, but with null parameter (
but the good parameter is in FaceContext ).
node.action() is not call either.
With fixed id it does'nt work either.
What is the mistake ?
Is it possible to do this sort of dynamic form ?
Many thanks,
Igor
