Description

Steps to reproduce:

with this kind of validation:

<mx:TextInput id="tovalidate" />
<mx:Validator
id="myValidator"
source="

{tovalidate}

"
required="true"
property="text"
requiredFieldError="Field Required"/>
<mx:Button label="clean errorStrings" click="tovalidate.errorString=''"/>

1. the TextInput is empty, hit tab to get out of it. valueCommit is properly fired. The
validator run and the error show up.
2. hit the button, the error is removed. everything seems ok.
3. go back to the button, hit tab again, valueCommit is fired, the validator run
but the error DOES NOT SHOW UP.

Expected Results:

the error should show up again

Workaround (if any):

do not use errorString, fire ValidationResultEvent programmatically like this:
var evt:ValidationResultEvent = new ValidationResultEvent(ValidationResultEvent.VALID);
myValidator.dispatchEvent(evt);

the bug seems located in validationResultHandler in UIComponent.as
in this test:
if (msg && validatorIndex != -1 && errorArray[validatorIndex] != msg)

using only errorString, we have still errorArray[validatorIndex] == msg,
the errorArray is not cleaned up, so we do not enter in the following line:
dispatchEvent(new FlexEvent(FlexEvent.INVALID));
so the TextInput does not show up the error.
