Expression Language error on startup using tree-demo sample
Can you help me figure out why I am getting a javax.el.ELException when I am using code from the sample tree-demo?
The server output:
Oct 10, 2007 10:49:39 AM com.sun.facelets.FaceletViewHandler handleRenderException

I have taken the index.jsp and converted it to a facelets-style xhtml page.

I basically just renamed the Bean class in the sample to RichTreeBean and that's it.
The Exception seems to be thrown when parsing this line in index.xhtml:
changeExpandListener="#{RichTreeBean.onExpand}""onExpand" is a valid method in RichTreeBean so I am stumped. Any ideas about what is causing this?
Thanks,
Rob
