Subject [jira] Resolved: (CAY-1071) NullPointer in BaseQueryMetadata while executing Queri
Date Tue, 05 May 2009 17:51:30 GMT


Andrey Razumovsky resolved CAY-1071.

    Resolution: Cannot Reproduce

This appears to be stale issue. I got similiar problem when working on CAY-979, but that was
with cloning EntityResolver, and there's nothing like that here. So the problem could be caused
by invalid query (or query root), or previous exceptions (that were not listed).

> The methode getEntityResolver() in DataContext says it could be null. I also recommend
to put the surrounding if-statement at the end of all if-else-statements, because all classes
are instances of Class.
