[Building Sakai] Using the Gradebook API

[Matthew Jones]

Hi Chuck,

I'm not sure if you're actually talking about removing the grade from the
gradebook or just clearing out the grade. I remember that mneme was using
the "null" idea you mentioned to clear out the grade and it was working
pre-2.6. I had to fix it when we went into production so it still worked.
The code was calling.

updateExternalAssessmentScore(String gradebookUid, String externalId, String
studentUid, Double points)

and was getting an NPE when the points were 'null'. Previously (and after
the patch in 2.6.2) it clears out the points. Perhaps what you're seeing
with your NPE is a bug, perhaps this is the function you're looking for?
