[Trinidad] managing selection in tr:tree

[Renzo Tomaselli]

Hi, while using a tr:tree component, I want to use selection for navigating in a separated panel. If I place a commandLink within the nodeStamp, then I can manage events and actions, however I don't know how to get the selected node identity. Then I tried to use the selectionListener attribute like the following:         <tr:tree value="#{dbTreeTrBean.treeData}" var="node"                 selectionListener="#{dbTreeTrBean.selection}" >             <f:facet name="nodeStamp">                 <tr:panelGroupLayout layout="horizontal">                       <tr:image source="#{node.image}"/>                       <tr:outputText value="#{node.description}"/>                 </tr:panelGroupLayout>             </f:facet>         </tr:tree> but the pointed method "selection" is *never* called. The basic idea was to force a submit on click and to manage the selection event to navigate. Adding the onclick introduced a full can of exceptions while expanding/restricting branches, such as "Cannot exit the root container", "row is unavailable", or just silent expansion misbehavior. Actually I'm using a straight ChildPropertyTreeModel as treeData. Without onclick expansion runs fine, but then I miss the timely selection. While I will investigate further about the wrong expansion, I still wonder if anybody succeeded in getting those events. Demos do not use them at all. -- Renzo
