// add whatever the first page widget is to pageContainer RootPanel.get("irisPage").add(PageContainer); Then to swap out: Widget currPage = pageContainer.getWidget(); pageContainer.remove(currWidget); pageContainer.add(createUserPageContent.loadPage()); That way you get the framework sort out the housekeeping for attaching and detaching widgets from the DOM. regards gregor > On Nov 27, 12:12 pm, Bhupen <[EMAIL PROTECTED]> wrote: > > > topLayout.printTop();
