[Contrib: Evaluation System] provider not being called

[Jim Eng]

I am following this discussion closely because we are hoping to move to a newer version of evalsys.  It seems to me that Aaron Z told us a year or so ago that the way the group provider works had changed at some point.  

If I recall correctly, in early versions of evalsys, the provider was consulted frequently while handling user requests.  In trunk (or 1.3.x), I think he said that the group information is stored internally and the group provider is consulted occasionally to update it.  That was done to streamline queries that matched users with evals by group membership, IIRC.  

Is this a correct description?  If so, your question might be why the group info is not being persisted adequately within sakai, rather than why the group provider is not being consulted in handling particular requests.
