Primefaces 3.5: trigger action upon expanding p:treeNode

[Aquillo]

I have a treeNode like this:

Code: Select all

<p:treeNode expandedIcon="ui-icon-folder-open"  
                     collapsedIcon="ui-icon-folder-collapsed">

Now I would like to trigger an action on a bean when expanding the node, something like this:

Code: Select all

<p:treeNode expandedIcon="ui-icon-folder-open"  
                     collapsedIcon="ui-icon-folder-collapsed"
                     action="#{bean.doSomething}">

Is this possible? If so, how?

look at the docu. You can use p:ajax event="expand".

Ah ofcourse, simple ajax event. Thanks for the solution!
