RichFaces Tree givingrendering error, classcast exception
Hello there
I am trying out the RichFaces example in my own program (which simply c onsists of a simple CRUD with just one Bidder entity with Id and Name. I have successfully managed to display a rich DataTable when I add Bidder but when I copy the RichFaces tree code snippet from the Exadel demo and modify it for my program, I get a rendering error and a class cast exception. Here is my bidderList.xhmtl :-
