Thanks I will try that. Haven't thought of a FilteredActivityMapper. I already tried a CachingActivityMapper on its own and because of the equality stuff it doesn't work.
I have just went through some examples but the layoutmvp example posted in this group also has an activity that starts over and over again on list selections (but data is local. If it was remote, everytime a request would be done) and the Expenses sample you have mentioned just has one activity mapper that holds one instance of its list and detail activities and calls updateForPlace(...) on them. So no new, clean activities..its more a singleton approach. Also there is no FilteredActivityMapper/CachingActivityMapper that wraps the ExpensesActivityMapper. Maybe you mean a different example? In mobilewebapp its not used either. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
