Can't delete parent

Hi All,

I have a couple of entities setup like this:

Foo <-->> FooItem

The "items" to-many has owns destination checked and a delete rule of cascade.  Then the "foo" to-one in the FooItem entity that points back to the parent is set to nullify.

Why then when I do this:

aFoo.delete();
ec.saveChanges();

I get a a validation exception like this:

ERXValidationException: A <b>Foo Item</b> must have a <b>Foo</b>.

these are some objects I converted recently to use the eo gap generation pattern.  I'm looking through my code and I can't yet find anything that would cause this.  The entities seem to be setup right.  But things are just not behaving as expected.

Any ideas where to look?


Thanks
Ricardo
