That's exactly the problem - it's a read operation and there should not be any 
write operation involved. However, it's hard to find out where the write 
operation in my code occurs, I can't find it in the view, maybe there's 
something in the authentication code, but I'd have to dig deep through my 
source. So It would be extremely helpful to know a faster way to find out 
what code triggered this warning.
