Regular Expression Validator Problem

Question

Hi,
I have a text area that I want to use a regular expression
validator on to verify that one or more 9 char alphanumeric serial
numbers were entered.
<mx:RegExpValidator
source="{entryField}"
property="text"
flags="gi"
expression="{/[a-zA-Z0-9][a-zA-Z0-9][a-zA-Z0-9][a-zA-Z0-9][a-zA-Z0-9][a-zA-Z0-9][a-zA-Z0- 9][a-zA-Z0-9][a-zA-Z0-9](
|,|\\n|\\r|\\t)/}"
valid="handleResult(event)"
invalid="handleResult(event)"
trigger="{entryField}"
triggerEvent="textInput"
/>
//for testing
private function
handleResult(eventObj:ValidationResultEvent):void {
if (eventObj.type == ValidationResultEvent.VALID)
entryField.setStyle("borderColor", "green");
entryField.setStyle("borderThickness", "2");
else
entryField.setStyle("borderColor", "red");
entryField.setStyle("borderThickness", "2");
The problem is the handler function always comes back
invalid, even when it should be valid, such as: 123456789 a12345678

Can anyone advise where I might be going wrong?
Thanks!

This is weird, i just tried your RegExp using the Adobe's
Live Docs example and it worked perfectly.
Try it at:
http://livedocs.adobe.com/flex/201/langref/mx/validators/RegExpValidator.html
Scroll down to the end of the page, then type your RegExp and
your TestValue and click the Validate button, it works. I am
guessing that maybe it is your
i
flag, try removing it from your validator.
Hope this helps
