you made a new QueryHelper qh so u expect that the new qh wil relace the "queryHelper" you configuerd in the faces-config but that's not true you have to replace it manually by replacing the old object with the new one.
if u don't want to creat a new QueryHelper object you may get the one you configuered from the session by:
QueryHelper qh=null;
qh=(QueryHelper) FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("queryHelper"); //get it from session if it was initialized.
if(qh == null){ // if it wasnot initialized yet
qh=new QueryHelper();
FacesContext.getCurrentInstance().getExternalContext().getSessionMap().put("queryHelper",qh); // put it on the session
}

Sorry, I'm a bit confused, but when do I have to use that (what return Statement do you mean?):FacesContext.getCurrentInstance().getExternalContext().getSessionMap().put("queryHelper",qh);QueryHelper qh = new QueryHelper();
And do I have to create a Object like this:Regards,Andy-----Ursprüngliche Nachricht-----

Betreff: AW: Problems with setting Variable in Bean
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.

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.
