The restrict test happens in mx.util.StringUtil. testCharacter() The restrict sequence is parsed for each typed char.
I am currently looking at the code. You might also have a look at it, if you have something ..

I found by experimentation that the following works, public static const RESTRICT_STRING_FOR_CSV:String = "0-9 a-zA-Z\&\"'~!@#$%*()\\-_+=[]|;:<>.?,\\^{}"; which uses ONE backslash to escape the ampersand and double-quote characters, but TWO backslashes to escape the minus sign (e.g. \\-) and the caret (e.g. \\^). However, I can't seem to figure how to escape the backslash character (I tried \\ and \\\ and neither worked). Is this making sense to anyone? Any idea how to escape backslash? ----- Original Message ----- From: [email protected] To: [email protected] Sent: Thursday, March 6, 2014 9:02:07 AM Subject: Re: how to mxml restrict with binding AS3 variable? Setting textInput.restrict=... in creation complete didn't change anything. There must be some difference or interaction between escape characters written in AS3 working in mxml. I need a programmatic solution, as there are so many places I can't manually write mxml code for each restrict. Any ideas? [Alex: not sure what you meant by "trace out the restrict property..." -- I'm testing by manually entering the characters in the text input field and seeing which ones work and which ones don't.] ----- Original Message ----- From: "Alex Harui" <[email protected]> To: [email protected] Sent: Thursday, March 6, 2014 8:33:07 AM Subject: Re: how to mxml restrict with binding AS3 variable? Don't use binding, set it directly in creationComplete/applicationComplete and see if you still have a problem. If so, trace out the restrict property from the TextInput to see if got modified somehow.
