JSPWiki sometimes seems to loose track of Anonymous/Asserted status. It happens frequently that, although the user is Asserted, the username becomes null.

You can try to simulate this like this:

• goto MyPrefs, and clear the preferences
• goto MyPrefs, dont change the name, just press Save Username

=> my local install gets lost (Asserted, username=null) v2.3.61 => JSPWiki.org v2.3.57 gives a HTTP Status 500 !? (mmm, seems I cant reproduce on JSPWiki.org) ( worse -- JSPWiki..org seems to screw up its cookies , and couldnt recover -- i had to clear the cookies to be able to continue ) (seems the AssertedName cookie was saved, but empty -> in v2.3.61 it is save with null)
