Subject: TextField Validation
I didn't get a response last time so I'll try it one more time. I'm having a
problem with TextField Validation
1. Is it possible to do validation of a character as it is typed in a Text
Field? I couldn't find a validation method and was wondering if I had to roll my
own Text Field similar to to the Spreadsheet example.
2. If there is a validation method how do you know where the cursor is currently
positioned and how do you signal rejection/acceptance of a character?

Hi Binky,
It's not currently possible to do validation as characters are
typed. However, this is a recognized hole in the TextComponent API
and is on the list of things to be fixed.
