New group settings: no error message appears while trying to invite a non-existing user.

I would suggest to add a dirty param redirect fix ala (&errormessage=KEY). Ok, the user can change the message, but for now this is ok, because we must find a better solution to deal with these errors (e.g. setting pages also have this "problem"; our current solution is too work-intensive), Maybe the FlashAttributes introduced in Spring 3 are a solution for our problem.

I at least added the error messages for now, I'll work on the param redirect fix today evening.

[Mario Holtmüller]

I added the redirect and a bunch of missing messages.

[Stephan Doerfel]

the particular issue is resolved. Daniel, would you like to create a proposal for a more general approach to a new workflow -- like indicated in your comment?
