I may be missing something, but saving objects with a parent child relationship under a transaction does seem to work properly. Attached is a simple example. It consists of one parent object with two child objects. When the three objects are saved outside of a transaction, everything works as expected. However when they are saved under a transaction, the framework saves the parent three times.

Yeah, it will do that... the business objects still return IsDirty = True until TransactionCommitt is called (just in case you roll back the transaction).  So, when the child checks its parent, it will still be dirty and will think it needs to save again.  Hrm... I'll have to think about this one; might take me a little while.  I do have a collection of the DataTables that have participated in the transaction already, so I can probably test on that.
