Hi Florijan,

I was involved with a Swing client/server project a while back that utilised 
the Remote Object Persistence part of Cayenne. We used ROP at its very early 
stage so we had a few niggling issues but overall I have to say I was/am very 
impressed with the speed at which one can setup the object model and get 
solid results.

We were able to develop MVC patterns that allowed us to build custom widgets 
which were "wired" into Cayenne. Once we devised an event driven mechanism 
for exchanging data, all one would need to do is set a Cayenne object within 
the controller and staticly tell the widgets which properties they represent. 
Data input/output and validation is sent using events.

I know that the team has since done a lot more work, especially with 
the 'trigger-like' functionality of Cayenne's ROP.

The project took a fair amount of work but keep in mind that for most of the 
participants it was the first real Swing application and an extremely 
ambitious one at that. Cayenne integration took a fair bit of the development 
time but mostly because it was in its early stages and because we were (and 
the team still is) pushing the framework to its limits.

I very strongly recommend Cayenne and ROP.
