I am trying to do the following:

I have a form with some fields I would like to modify using a ChildFormDialog.  I have setup all properties and it is working just fine when adding, editing this record, the information is translated back to the parent form, but when I try to Undo it will perform an Undo in the whole record including data in the parent form. 

Is there a way to control what fields to Undo in the translated BO in the ChildFormDialog?

So far, I have not find a way to just undo specifics fields in the BO.  Since this ChildFormDialog will only modify 5 fields of this BO, I may need to create these properties in the form so I can have control of Undoing any changes in the ChildFormDialog.
