Sorry I forgot the link: http://www.javaworld.com/javaworld/jw-07-2004/jw-0719-jsf.html
and the code is http://www.javaworld.com/javaworld/jw-07-2004/jsf/jw-0719-jsf.zip with the FacesUtils class under: src/java/catalog/view/util If you have licensing problems (the code is under no license) I have a mail of Derk Shen himself which basically gave me permission to get that class under Apache 2.0, so send me a private mail if you need an Apache 2.0 licensed version of that class, I will send you the code and the confirm mail this evening. (Dunno what to do with it now, since I do not know if MyFaces is in need of that class, it would introduce a central dependency into one single class, which might not be feasable) Werner Werner Punz wrote: > QueryHelper qh = new QueryHelper(); ---> HERE I'm making a new Object > of the second bean!!!
