Andrus Adamchik commented on CAY-1071:
--------------------------------------

So why is "resolver" null? Could you post a full stack trace? It shouldn't be null under normal circumstances.

> I figured out a problem (NullPointerException) in Line at org.apache.cayenne.query.BaseQueryMetadata.resolve(BaseQueryMetadata.java:100) in  BaseQueryMetadata class. The resolver in line 100                     
> entity = resolver.lookupObjEntity((Class<?>) root);
> is null and there is no check if there is so. 
> 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.
> Hope I could help you, and you fixe the problem as soon as possible, because I want use cayenne for myself.
