Very nice!
Now if we could do this kind of scaffolding without having to step outside Java proper ! I don't want to learn Groovy, even though it is obviously Java-related and Java-like. I have built a simple application to interact with GAE and PayPal (http://2010-en.concordia-international.org/registration). I used Siena for persistence because it was completely trivial. Now if only I could get automagic containers and UI based on a trivial model, I'd be in heaven.
Thank you Jean-Francois,
Actually I made this framework because I faced difficult situations: My developers mostly fresh-graduates, and it's very hard to find Java developers in Indonesia.(even 'Java' is in Indonesia but you can find millions VB and PHP developers there), so I should take a 'pragmatic' approach, how if we could build a Java web apps, enterprise ready and have a great UI?..and easy to program like VB programming? So I mix Grails + Vaadin then make some helper codes to ease those ex-VB and PH developer jobs.
Currently this framework is being used for small ERP application called RTM, I also planned to use this for making a financial service/banking application
Really great work!
I tried out to the code but found some issues while working with the sources. Is it possible that grails/conf-folder is currently missing?
Additionally I the setMainWindow in VGrailsApplication is unimplemented.
If possible somehow, can you provide a solution for these issues, thx in advance!
-- cheers, volker
This is my stumbling block at the moment.
time.InvokerInvocationException: java.lang.Exception: Integrity constraint violation - no parent FK1C92FE2FF3744CB2 table: ROLE_TYPE
Not sure if this is related to NOT using mysql?

?? grails install-plugin dbunit-operator may automatically install a copy of dbunit? not sure.

It's really a very good job. I recently check out the source code. When trying to run the project, I get an exception:
Did you remember to setMainWindow()
I think this is required for newer versions of vaadin than the v1.0 you are currently using. Can I use the framework in this case??
I'm really interested in this project. It would be great if I can try it in a simple way. I need some help :grin:
Thanks in advance
