Subject Problem in Tree2: nullpointer org.apache.myfaces.custom.tree2.UITreeData.encodeEnd
Date Wed, 27 Jun 2007 18:36:20 GMT

Hi freinds,

I have implemented tamhalk tree2, Initially it was working fine but now It
is throwing nullpointer when treis to render the tree. 

Pls help me. here is the JSP page code for the tree to be displayed and
stack trace of the exception.

Does any one have any idea?

Here is the faces config file.

Thanks and Regards,
