Hi everyone,
I have developed an application within the portlet container GateIn.

I have a problem at login.
The login is successful 1 or maximum 2 times. If I try to login for the third time, the login popup where I insert access credentials, appears on the screen and disappears immediately. In this way, I do not have time to enter userid and password in the popup.
I fix this problem temporarily by clearing my browser cache.
After emptying the browser cache can make another 1 or 2 login, then logon to the third problem occurs again.

Has anyone ever encountered such a problem.
Possible solutions?

Thanks in advance for your help.

Bye Bye
