Ya, this one is a real hard one. Previously my gut feel was that we didn't want to expose the editor, but I've done a 180 on it. I think the implementation will actually be cleaner, but also it keeps us from having inconsistency between TextInputControl and ComboBox. If we had mixins in Java (like in JavaFX-Script) we would have done TextInputControl (and Labeled!) as mixins and then we wouldn't have this issue as ComboBox could implement that mixin directly. But as it is, I think having getEditor() would be the best. Note that a developer can customize the skin of an editor of a ComboBox via CSS, so you can totally customize what the skin is like. The ComboBox skin doesn't really care -- as long as it can be resized and changes in text are observed and mutable it is good to go.

My gut feeling is to not expose TextField / TextInputControl directly to the user. However, my main driver for getting this done is for the Scene Builder team, who want access to the entire TextInputControl (and realistically, the TextField itself).

If there are any strong objections, please let them be known (even if you've registered an objection already). If I don't hear any strong objections, I will assume an implicit approval has been given.

Correct me if I am wrong but that also sounds like requiring another control using such a TextArea based skin. If that is true than nothing is lost by exposing TextField on ComboBox. Also, I have never seen a multiline text combobox - can't be very common.
