[samigo-team] SAM error wrt to listener.author.AuthorActionListener

Wed Oct 23 06:20:12 PDT 2013

Thanks Karen. We are using the 2.9.x version of Samigo from revision 113710.  It’s been modded for calculated questions per our developers that part did not touch the AuthorActionListener.java code.

Thanks,
Narasi

Hi Everyone,

We are seeing this issue wherein when anyone with  instructor type role access Samigo an error report is thrown out error report posted below.

On looking at the course backup I am seeing 4 of her exams does not have an author – would that cause this error? If it possible to insert an author into an exam if the field is blank and thereby fix this issue? Any recommendation to overcome this issue will be greatly appreciated.

Thanks,
Narasi
