Yeah, I have thought the same thing as I was implementing MVP/CommandPattern. I have a few eventbus events that I handle with EventHandlers, but then I have the whole gwt rpc mechanism that uses my own generic action classes.
Combining the two might be a good move, however it might get tricky crossing the great wall of javascript. I am no gwt expert, so I don't know how tight a coupling you can get from your server side stuff and GwtEvent (assuming you still want to use eventhandlers). I am sure its doable though. -pj On Tue, Sep 29, 2009 at 3:37 PM, Chris <[email protected]>wrote: > > Just had a quick question...
