I set up an application with appfoundation, everything is working fine, except the UserManagement. I was debugging my application to notice, that at some point (I can not figure out what it is connected to) the function
SessioinHandler.get()returns null, although before it returnd a valid User object. And
SessionHandler.setUser(User user)
is never called.
Even stranger, some time later (again not knowing when) get() returns the same userobject as before again… 
Does anyone have an idea what the cause of this problem might be? Can it be connected to the ThreadLocal class SessionHandler stores its user object in. Might I suddenly be operating on a different thread? would that be relevant.
I am using ICEPush as a major addon i could imagine influencing the SessionHandler behaviour. No other ideas…
Any Help or hints where I could search for solutions are very appreciated.

Niklas
