Hi there,

Say I have entities Foo and Bar (both of which have an attribute isDeleted) and a join FooBar and I create restricting qualifiers for Foo and Bar of (isDeleted IS NULL OR isDeleted = 0).

Foo.fooBars() still fetches all fooBars even if pointing to a Bar that cannot be instantiated due to the restricting qualifier.

So my question is: should EOF filter such joins automatically (i.e., should I file a bug) or is it just up to me to auto-apply these restricting qualifiers?


I would expect that to work for fetches. In the past I have had a relationship to a subclass in a single table inheritance hierarchy, and I recall that only the correct instances were fetched. I can't see why this should not work, I'd file a bug.

Have you checked the SQL and verified that they restricting qualifier is not getting generated?

Chuck
