Re: GWT MVP Activities and Places

I am not too sure of the final goal but I have two sample projects
that do something similar using places with parent class (sub-class
defines main content activity, and parent class defines a different
area that does not update every time)

Both activity mappers are wrapped in a cacheActivityMapper

Not sure if this will help you or not
