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.
