True its WidgetCollection that has a 'contains' method but a
RootPanel.get returns a RootPanel object which is a sub-class of
ComplexPanel.
ComplexPanel has a getWidgetIndex methods which return -1 for
getWidgetIndex(Widget) and null for getWidgetIndex(HasWidget) when the
requested object isn't in the widget list. You can derive your own
'contains' logic from the above.
Its purely a matter of style, but I'd personally prefer to avoid having
extra state flags to manipulate and would rather use state that's
already in the data of the object in question.

There is no contains(widget) available like
RootPanel.get("id).contains(widget).

How about:
if (!RootPanel.get("id).contains(widget)) {
RootPanel.get("id").add(widget);
Because of the nature of javascript and web browsers the above
call is inherently "thread safe".

I am making 2 seperate RPC calls.
Whichever is finished first, i would add
RootPanel.get("id").add(widget) into onSuccess.
I can not add same widgets two times in both onSuccess(). So i am
out of mind how to resolve this.
Any logic pls.

Its not possible to stop execution as RPC requests are async.
The only thing you can do is to put your code that has to
wait into the onSuccess method of your RPC call.
