HI I would like to have a look at the JsfUtil class but I can't find it. Please could explain it in more detail where we can find it. Thanks a lot.

The methods of the object qh fill some SelectItem[] Variables... this is your problem, you should use the jsf variable resolver mechanism to take care of the backend bean generation. I can recommend to use the excellent JsfUtil class you can find on www.javaworld.com and in appfuse, which encapsules all the mechanisms. This class has a getManagedBean method which takes care of all that.
