I have a dataform using a custom DataFormCommandProvider. The CommandProvider has an overriden CanAddNewExecute() function that always returns true.
When I first go to the page with this control I can Add New items all I want. However once I edit an item, and commit or cancel the edit, the add new button (which is still enabled) stops working.
In debug I can see the CommandProvider's AddNew() function is getting called; the only difference is in the beginning the Dataform.CanAddItems property is true. After the Edit, the Dataform.CanAddItems property is false. I believe that while it is false it will not do the AddNewItem functionality.
How can I get the Dataform.CanAddItems property back to being true after an edit, so I can continue adding items?

I am seeing this same behaviour when not using the custom DataFormCommandProvider as well.
Could it be an issue with the underlying source collection?
I am using an ObservableCollection, exposed through a CollectionViewSource.
We can add new until we edit, then we can no longer add new.

looking a bit deeper, I notice this is only happening when the edit is canceled.
Anyone have an idea what is going on?
