Mike Kienenberger commented on CAY-1880:
----------------------------------------
The problem appears to be in DataDomainQueryAction.interceptRefreshQuery().
If there's a domain.getSharedSnapshotCache(), we clear it for refresh-all, or
send notification events, but we do nothing if there is no shared snapshot
cache.
What needs to happen is that the context's objectstore should be appropriately
adjusted when there's no shared snapshot cache.
The following patch makes this change and passes all tests.
