Does the validator fire when you check the
checkbox and it’s just that the error doesn’t clear? Or does
the validator not fire when you click on the checkbox?
If the first it sounds like a bug, you
could workaround it by adding a validate handler and setting the errorString on
the checkbox to null if there are no errors.
<customValidators:CheckboxRequiredValidator
field="fieldValues.DonationConfirmation"
required="true" validate=”if (!event.validator.hasErrors()) DonationConfirmation.errorString
= null;”/>
I think that the Checkbox does clear its
error messages though so I’d make sure that your validator is really
firing and doing the right thing.

Hello. I have a form in an application I'm building that requires
the
user to check a CheckBox that acknowledges they
read a statement. In
order to check that the CheckBox has been checked,
I created a custom
validator. The validator works fine, but the
problem I have is that
when the user checks the CheckBox, the error
message does not go away.
The code for the validator is below.
Thank you,
Sean
class CheckboxRequiredValidator extends
mx.validators.Validator
{
public function CheckboxRequiredValidator()
{
}
public function doValidation(checkboxValue):Void
{
CheckboxRequiredValidator.validateCheckbox(this,checkboxValue,required,null);
}
public static function
validateCheckbox(validator:mx.validators.Validator,
checkboxValue, required, subfield):Boolean
{
if ( required
&& !Boolean(checkboxValue))
{
validator.validationError("notCheckedError", "This checkbox must
be checked.", subfield);
return false;
}
return true;
}
}

<mx:Model
id="fieldValues">
<DonationConfirmation>{DonationConfirmation.selected}</DonationConfirmation>
</mx:Model>
<customValidators:CheckboxRequiredValidator
field="fieldValues.DonationConfirmation"
required="true"/>
<mx:CheckBox
id="DonationConfirmation" labelPlacement="right"
selected="{formModel.DonationConfirmation}"/>
