Has anyone received an error in Flash Builder like this?

[Guest]

access of undefined property variable01.

access of undefined property pattern.

I don't see a problem with the code, yet the error persists.

<?xml version="1.0" encoding="utf-8"?>

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

               xmlns:s="library://ns.adobe.com/flex/spark"

               xmlns:mx="library://ns.adobe.com/flex/mx"

               creationComplete="init(event);"

               minWidth="955" minHeight="600" backgroundColor="#cbd8e6">

    <fx:Declarations>

        <!-- Place non-visual elements (e.g., services, value objects) here -->

    </fx:Declarations>

    <fx:Script>

        <![CDATA[

        var variable01:String;

        variable01 = "1";

        var pattern:RegExp;

        pattern = /^[0-9]{1,3}$/;

        pattern.test(variable01);

        ]]>

    </fx:Script>

</s:Application>

When using Flex you can't just put code in a script tag like this. While declarations (public var etc) can be in this scope, logic must be inside an event handler.

Thanks for your help. I will study the creationComplete event and try it.
