Re: Issue 5801: Handle Validation Groups

OK, but that would mean: I have to modify the GWT-s Requestfactory (to entirely replace it with my own implementation). Right?
There is no constructor that allows me setting my own SimpleRequestProcessor.

I think, in that case it would be better, not to change the GWT-s code, but to catch the ContraintViolationException when persistence provider is called and to return an object with constraint violations inside indicating if request was processed properly or not. That will cause calling client's onSuccess() method, instead of onConstraintViolation() but in my opinion it is better than modifying the GWT-s code.
See last comment in this post:

Thank you very much for helping me to understand this process.

So now:
How do I propagate ConstraintViolationException from my CustomRequestFactory correctly to the client so that Receiver.onConstraintViolation() is called on the client?

As already said you should customize RequestFactoryServlet to use your own version of SimpleRequestProcessor. SimpleRequestProcessor already has validation code and you would need to adapt this code for the service invocation. Basically you must set violations into the ResponseMessage.
