Session userdata disappearing after session updates

[eluser]Ricardo Rodrigues[/eluser]
I'm not using any Authentication libray just my own control.

I have a Login form in which the control is made. If I made the view reload itself, I have all session userdata but if I redirect to main view, it looses it.

I'm 3 hours debuging this and found that is the DB check that is failing and making session to destroy. Why it fail....

I disable the reset in the Session library but the userdata is missing!
