[Using Sakai] Assignment problem clicking on returned submission

[Anders Nordkvist]

Hi,



I have a problem with the assignments-tool when clicking on returned submissions for one assignment. Whenever I click I get to file a bug report and this error (below). Can anyone see whats going on here?

I suppose its some kind of NullPointerException but I don't have a clue how to solve It!



Ps. I havn't found any open jiras for this problem.
