Re: Session timeout NPE

After some further analysis...it is not isolated to JSF tools.  The 
problem seems to occur when a POST is sent following a timeout, 
regardless of the tool.  The LoginTool handles the POST with doPost as 
if it came from the LoginTool form, even though this may not be the case.

Attached is a patch (not sure if it is the *best* solution, but it 
works) to resolve this for sakai 2.1.2.  Although I haven't checked the 
issue in 2.2, the code still looks the same and the patch should work 
there as well.  *Note* nobody has verified that this is an issue for 
them as well, so it could be something funky with our code/configuration.
