after loading test.zul I have a listbox with 4 pages ... I move to page 4 and now click on tlbtn_test so the model of listbox is updated BUT ACTIVE PAGE REMAINS ON THE PAGE 4.
this behavior (for me) seems illogical ... if I have PAGING LISTBOX, when I update/set the model by new search, the current page by default should be set to the first page without having to make: this.lst_test.setActivePage(0) !

BTW, would be nice to have in new ZK 6 version an option/attribute in zul file to decide whether or not to return to the first page after set/updating the model of a PAGING LISTBOX or PAGING GRID.
