Re: GWT 2.1 Activities – nesting? YAGNI ? - an example of where you NEED it !

I think in the case of the composite activity / composite place, you
need to define how closely realted each workspace will be. will there
be any overlap between sub/areas of one workspace and a different

You can be careful about how you craft your composite place and how
you tokenize it into sections. one section for each area that holds
the state. then each sub area widget/activty can cache it's current
state and do a really quick check to see if the new section of the
composite place for it's area is different from its current state.

It would probably take a good deal of organizing a pattern and
wrapping your objects in the right way
