I have a custom node data class, with a node location property. My class has implemented INotifyPropertyChanged and is raising events with PropertyChangedEventArgs populated with the property name.
This by itself doesn’t seem to be enough to have the Undo working properly for the node position changes.
I a test application, what I found is that I have to raise the property change notification with Northwoods.GoXam.Model.ModelChangedEventArgs.
This is an issue for me because I inherited an existing data class that I am using for node data. If I have to raise property change notifications with GoXam event args then I guess I have to sub-class and re-implement all the property change notifications.
Is there a different way to get the Undo for node location to work properly?
