I have a business object on a parent form that is configured SetDirtyOnEdit = False. It is also configured to raise the FieldPropertyChanged event. This object is placed in Edit mode on the parent form and a childformdialog is called. When the fields are edited on the childdialog the IsDirtyChanged event is never raised, but the FieldPropertyChanged is and the IsDirty property on the BO is updated. I can't figure out why the IsDirtyChanged event is not being raised. I'm using SF 1.7.3.4.
