I am using rich tree as navigation. I would like to ask, if there is any possibility to rerender some area on the page when tree node is expanded. The nodes of my tree are made by commandLinks, when click the commandLink, I rerender content area of page. When I click the expand image, I want it to behave the same. Is there any way how to do it? I see there is attribute inside rich:treeNode called onexpand, can I force to rerender the area by using this attribute?
Did you try
<a4j:support event="onexpand" reRender="id of your component" />
