I'm trying to customize the RichTextEditor by removing some controls. I've been able to successfully remove a number of them (alignButtons, colorPicker, etc.) but when I do a toolbar.removeChild(underlineButton) I get the following error:
ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller. I don't see any notes in the documentation indicating that this button is removed any differently than the other controls. Am I missing something? TIA for any help!
