Validation errors exiting from current process.

Question

Hi All,
   I'm having below code
   <mx:Canvas height="100%" width="100%">
     <mx:VBox width="100%" height="100%">
         <mx:HBox>
             <mx:Label text="Consumer Information: " fontSize="12" fontWeight="bold" color="#34B05D"/>
         </mx:HBox>        
         <mx:HBox width="100%">
             <mx:Label  width="25%" text="City: " fontWeight="normal"/>
             <mx:TextInput width="25%" id="city" editable="{pageModeStat}" />
             <mx:Label  width="25%" text="State:" fontWeight="normal"/>
             <mx:ComboBox width="25%" id="state" enabled="{pageModeStat}" />
         </mx:HBox>
         <mx:HBox width="100%">
             <mx:Label  width="25%" text="Zipcode: " fontWeight="normal"/>
             <mx:TextInput width="25%" id="zip" editable="{pageModeStat}" />   
             <mx:Spacer width="25%" />                
             <mx:Spacer width="25%" />        
         </mx:HBox>
          <mx:HBox width="100%" horizontalAlign="center">
             <mx:Button label="{buttonText}" id="submit_search" click="submit(event)"  />
         </mx:HBox>
   </mx:VBox>
     <mx:ZipCodeValidator id="zipCodeValidator" triggerEvent="click" source="{zip}" property="text" valid="zipCodeValidator_valid(event);" invalid="zipCodeValidator_invalid(event);" />
  </mx:Canvas>
   I'm having following method in <mx:Script>
   private function zipCodeValidator_valid(evt:ValidationResultEvent):Boolean {
        //Alert.show(evt.type);
        return false;
    private function zipCodeValidator_invalid(evt:ValidationResultEvent):Boolean {
        //Alert.show(evt.message);
        return true;
    public function submit(evt:Event):void{
          if (zipCodeValidator.validate(zip.text))
             return;
          myViewStack.selectedChild = Confirmation;
    }//End of submit
   When user submit this form without giving any zip code/invalid zip code, I'd like to validate this in submit method and need to redisplay the same page if it is having any errors. When I give valid zip code it is still not displaying 'Confirmation' page.
   Can anyone let me know how to use zip code validation in this scenario.
   Thanks in advance.

Answer 1

Can anyone let me know how to do validation in Flex, I think this should be simple one.
Like whenever there is any validation error then it should exit current process to display error messages, if there is NO validation errors then it should process normally.
Thanks in advance.
