Hi there, I am somewhat of a GWT novice and I am attempting to create my first application and I would appreciate if any wise old sages would be able to offer some guidance... As part of this application I want to offer offline functionality. My thoughts on how this will work are as follows: > User logs in > Credentials checked on server > If ok, check client DB exists (if not, get DDL from server) > if the server DB has been upgraded apply changes to client
There are more steps to follow, but hopefully you get the general idea of what I am trying to achieve. I have been able to use RestyGWT to connect to PHP scripts and transfer JSON back and forth and I have also been able to use GWT Mobile Webkit to create and interact with a client DB. However, I am now a bit stuck in that I am unsure what the best way is to glue it all together as I am used to synchronous things... The easiest option I can see would be to daisy chain the callbacks together so that all required steps get executed in the required order. However, that seems rather inelegant and so I was wondering if there were any better options out there. I thought about an event for each step, but from what I have read, that appears to not be the done thing. I am also slightly confused as to what the best way to interface with the results of the callbacks, say if some other part of the application needs to make use of the results. Any advice would be very much appreciated! Cheers Tim -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
