Hi Guys,
I think the issue over here is, in such cases we need a new scope(workflow scope).The
existing scopes(request/session) do not suffice in such cases.
The session scope can be used but it may not be cleared.So there has to be a solution
at architecture level.And the struts workflow
The whole point is there is no concept of a Workflow scope in Servlet API and if you
want to share objects , you have to put them in session.And then clearing them is not
always easy, as you will never be clear when user may leave the workflow scope.And you
have to code for it in every action.

If the user has multiple windows open all sharing a session and does
different things in different windows things get really fun.

If user has different windows in different windows, then only the latest windows
