Hi Bhupen,
This looks suspiciously like it might be the cause of your exception.

Suppose you did it something like this (SimplePanel can only have one
widget):
SimplePanel pageContainer = new SimplePanel();
// 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.
