CM Qualifier (or Declared Qualifier) is not honoured in 100% cases
------------------------------------------------------------------
Key: CAY-1005
URL: https://issues.apache.org/cayenne/browse/CAY-1005
Project: Cayenne
Issue Type: Bug
Components: Cayenne Core Library
Affects Versions: 3.0
Environment: ROP, LOCAL_CACHE, paging. Derby db.
Reporter: Marcin Skladaniec
Assignee: Andrus Adamchik
I have a suspicion that the qualifier set in the modeller is not always
incorporated in query.
Occasionally we are getting an exception like this (not only against this
record) :

matching row exists in the database for ObjectId: <ObjectId:Node,

Model defines a qualifier for the Node entity : (isDeleted = null) or
(isDeleted = 0). I checked the database and the Node which caused the trouble
has isDeleted ==1, it should never be fetched in the first place.
I was not able to isolate a test case, it is only my guess that there might be
a bug.
