We launched LiveCycle Data Services (LCDS) 3 public beta yesterday on http://labs.adobe.com/technologies/livecycle_dataservices3/.
We have beefed up tooling and simplified developing flex application development. You can now develop new fully functional flex applications with no server code in under 10 minutes. We have a few videos to help people get started http://labs.adobe.com/technologies/livecycle_dataservices3/videos/, and plan to add more (I am on the hook for one or two).
Now is the chance for folks to try out the new Data Model development features we have added and give us some feedback.
