Ah I see, the point is to avoid the extra round trip time of the first RPC call. For most cases, it's probably not worth the extra effort and complication - note that most web pages make many many more round trip calls to load all the images etc. In that video, it sounds like most of their services return a simple HTML string that they push into innerHTML, which would be straightforward to bundle with the initial code download. This becomes more complicated with real data.
So I think the correct answer is, try it the straightforward way (just make the RPC call), and if you find the performance unacceptable then look into something like this - especially for someone just learning GWT! -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
