I am trying to add SGWT datasources to my existing Grails domain classes (~beans).
Since the SGWT-Grails plugin is broken at the moment, I reverted to the hibernate DS integration strategy as this seems to be able to leverage the existing bean definition. This is the DS description file for one of the domain classes:
The corresponding domain class (~bean) reads (stripped to the bone):
Alas, there is a
on startup.
This post might describe the problem and suggests a fix:

So is there a way to influence, how the Beans are loaded from the SGWT (server-) side?
Or is there an even better strategy to add SGWT Power features to an existing Grails application using existing domain classes as a base (SQL datasource is no option due to existing business logic)
Thanks
