Re: Detecting inactivity on the client


My solution to this problem was to implement polling to the Servlet
layer, based on events that were fired. So if no event was fired the
would timeout and jump to another page.
Since all my user events go through a common event bus
(BasePresenter), this
is easy to accomplish.
