> Imagine there is many-many rel between tables A and B using join table C (no ObjEntity). There is flattened rel bArray from A to B with delete rule cascade (if that matters) but no reverse. 
> Adding to such rel goes perfect:
> INSERT INTO B
> INSERT INTO C
> But deleting B does 
> DELETE FROM B
> which obviously fails.
> Haven't digged into code much, but it seems arcDeleted() isn't invoked for B and therefore relationship isn't recognized as flattened.
> Since reverse rels aren't mandatory in Cayenne, this should work
