Thank you for the so far posted replies. For maybe further clarify:
- I need this to work only at the start up of the application, to wait till my model has all the data and then update the GUI. - I am using mGWT, still the architecture is GWT related. I am using mGWT to get it cross-device and GWT to get it cross-browser. (of course with its limitations) - let's say I can control the RPC calls, what do I do with all the events? Can I control my application only to move on when all the necessary events are done? @Alfredo - if not gwt-rpc, then what?

This saves a lot of network overhead.
