Susan,
The
reason that it is not static is because most validators have properties that
help define the validation rules. For example, the Number validator has a maxValue
and minValue property. Also, you can customize the error messages for each
validator. Thus, we need instances of the validators to accomplish this.
As for the “errorString”
property, it is better to use the UIComponent.validationResultHandler function
instead. Just pass in the results from the validate() function.

Validator woes
Jason,
Thanks. I guess I just got mixed up since it's a little unnatural to
instantiate a class to call a method that should be static! Also,
adding text to the "errorString" field automatically sets everything
redhere's my method should anyone search upon this message at a
future date:
private function validateField() : void {
var emails : Array = toField.text.split(",");
for(var j:uint=0; j < emails.length; j++)
{
var emailVal : EmailValidator = new EmailValidator();
var valResult : ValidationResultEvent =
emailVal.validate(emails[j]);
if(valResult.type == ValidationResultEvent.INVALID)
{
toField.errorString="'" + emails[j] + "' is not a valid
e-mail address.";
return;
}
}
}
