Please could explain it in more detail where we can find it. Thanks a lot. mfg Hans Sowa PROCON DATA Datenverarbeitung Ges.m.b.H. mailto:[EMAIL PROTECTED] http://www.procon.co.at -----Ursprüngliche Nachricht----- Von: news [mailto:[EMAIL PROTECTED] Im Auftrag von Werner Punz Gesendet: Montag, 24.

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.
