I have a partial fix for this problem. Its gonna fix uni-directional delete dependencies between different classes. The remaining problem would be cascade deletes on uni-directional self-relationships. I still have to do all necessary actions to get it integrated, which might take a few more days. We also gonna push for it to get into V2.
