how to i persiste state??

hi..

i've read about the MVP / place framework, but from all of this i still don't understand how do i persist the state of view i'm LEAVING, so it would mainted on the url, i have no reference the to place i'm leaving from

all i have is the getActivity method with it's place parameter of where it should go.

what i'm trying to do, is to create a 'dynamic' basic place, because if i would go the gwt way of creating MVP i would have to:

1. sub class new Place
2. create a tokenizer for it (even if half my activities have context that's still a lot  )
3. register the tokenizer in the "withTokenizers" annotation.
4. create the activity
5. create the view.

step 1-3 could be avoided if i create one basic activity, that would receive a prefix AND context, thus i would have only to create one tokenizer that would get the token (with my prefix and context) and create a new Place with the context.
