Dear WinObjC Engineers,

It is not in: UITextField.mm

Can you explain the scenario that you are using the API for. Is it possible to workaround this by subscribing to the TextChanging event on the underlying XAML TextBox?

@tadam-msft It is being used to mark when text has changed for the purpose of a later commit if the mark has changed (is true). I suppose a XAML event processing token can be installed for this purpose. But, it seems that is something that a framework designer and/or developer (Microsoft) would want to do and it should not be done at the app level. I mentioned this issue, in a larger context, to Raj and Arnaud already on 2/8/2017. The workaround here for this present issue is to simply commit every time; but yeah, we are already installing XAML event tokens for other things so that can probably be done in this case as well.
