Hi Odeyemi, See slides 32-47 here: http://www.slideshare.net/turbomanage/whats-new-in-gwt-22
Also, this sample project has two ActivityManagers showing how the same Place can be mapped in both (albeit one is null). http://code.google.com/p/listwidget/ Inline comments below...

Instead use historyHandler.handleCurrentHistory(). The rest of the code in your getAgentProfileActivity() method should be run during application setup (called from onModuleLoad, not a ClickHandler as shown here).
