Try to think about this...What mean "cascade" ? Cascade mean that the action applied to the relation owner is applied to the other side of the relation. So: - if you save a Product NH will save the Image - if you delete a Product NH will delete the Image and so on.
The issue NH-1262 perhaps can be implemented because the one-to-one is a bidirectional relation but your case is completely different. Your relation is Product-to-BinaryContent and BinaryContent has a different autonomy lify-cycle. Is the class BinaryContent used in some other relation with other classes ? 2009/8/3 Dmitiry Nagirnyak <[email protected]> > Anybody please? > > 2009/8/3 Dmitiry Nagirnyak <[email protected]> > > Noo!
