Good point Thomas. So, the place service would directly call some presenter or talk to the presenter by events. Considering my sample application and the url ( http://host/bit.html#edit;issue=1 ): - the place service would fire an IssueEditEvent with the issue id=1 - the main presenter would take this event and call the appropriated method in the IssueEditPresenter Thanks for the feedback Mr. Broyer, I will make a mix of the gwt-presenter project and mine, implementing this place service as well.
