QueryHelper qh = new QueryHelper(); ---> HERE I'm making a new Object
of the second bean!!! 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.
