OK, there was a bug in Gatein 3.1.0-GA and we have fixed them in 3.2.0-GA releasing coming soon
i saw another bug in login screen.
If you type "são" (without quotes) as user name and try to login, the screen is re-rendered and the user name is changed to sÃ£o, if you try to login again the user name changes to sÃÂ£o and so far.
The next version of gatein will fix this bug too?
thanks in advance and best regards.
