Restrict ,.(comma) for multiple numericstepper in a page

Question

Hi.
i am trying to restrict ,.(comma) in numericstepper , i am bale to achieve it by using
<s:NumericStepper id="datastoreCountInput" fontWeight="normal" creationComplete="validateTxtInput()" ..............  />
my validate function is
private function validateTxtInput():void {
  datastoreCountInput.textDisplay.restrict ='0-9';
my question is i have multiple NumericStepper in my page i wanted to use the same function for all of them . so i wanted to pass the current NumericStepper  object/id to the function.
so that i can use the object in place of datastoreCountInput and restrict teh input value. As i am new to flex . looking for help here.
Thanks in advance

Answer 1

ok i figured it out , below is the code if anyone else is looking for it (but you need to have default value set if user left blank )
In my case it will be always default value will be 1 if it is blank , so it works
