Problem with RichTree Component

[aymenez]

I looked at http://livedemo.exadel.com/richfaces-demo/richfaces/tree.jsf and I built the same  example(http://livedemo.exadel.com/richfaces-demo/richfaces/tree.jsf?tab=model).

I just copy the source code without changing anything. The tree is well displayed but I have problem with nodeSelectListener.

Error: [lifecycle] /TreeBean.xhtml @18,260 nodeSelectListener=”#{simpleTreeBean.processSelection}”: java.lang.reflect.InvocationTargetException

Could you give me some advice?
Thanks!

If you give some more stacktrace. Provide bean source.
