Question

I’m using the primefaces[3.4] showcase with tree and checkbox selection:

http://www.primefaces.org/showcase-labs/ui/treeSelectionCheckbox.jsf

Is it possible to attach a p:ajax event for click on node’s label??

I need to update a panel with children objects when user click over tree’s nodes labels, not necessarily when user select them (click on checkbox).

Thanks in advance.

This is how I workaround this, just adding a checkbox inside the treeNode template and changing the selectionMode to single.

<p:tree value="#{treeBean.root}" var="node" dynamic="true" cache="false"  
            selectionMode="single"  selection="#{treeBean.selectedNode}" id="tree">  

        <p:ajax event="select" update=":form:messages" listener="#{treeBean.onNodeSelect}" />  

        <p:treeNode>  
            <p:selectBooleanCheckbox  id="treeCheck" value="#{node.selected}"/> 
            <h:outputText value="#{node.name}" />  
        </p:treeNode>  
    </p:tree>  

Consider that you have to code manually the logic to check/uncheck parent/childs nodes when it should.

Thanks.
