So I am noticing this weird behavior with a TextInput in Flex when I have the maxChars property set on it. For example, maxChars=”1″.

If you have this set and have 1 character in the TextInput and then press another key nothing will happen because the max characters are already in there. However, if you press the Insert key and then press another key, that character will show up in the TextInput, leaving you with 2 characters in a TextInput which only allows 1 character max.

I believe this is happening in all TextInput’s not just custom ones.

Anyone have an idea of how this could be fixed? Some method I can override in a custom TextInput to override this behavior?

Thank you!
