[Building Sakai] Mneme Gradebook error

[Jon Higham]

We are running Mneme 1.2m1 on Sakai 2.6.0 and get an error on finishing
a test in Tasks, Tests and Surveys (Mneme) when the test has the
following setup:

                Release Grades - Manual Release selected

                Send to Gradebook - checked

 

Other combinations of Send to Gradebook and Release Gradebook work. I've
copied in the error below.

 

I don't know whether this could be related to SAK-7745, or whether Mneme
1.2m1 isn't ready for 2.6 as it is not mentioned at
http://etudes.org/mneme/download.html.

 

 

Thanks,
