"Error #1006: getAttributeByQName is not a function." Flex 2.0.1 hotfix 2

Question

I am working on some old Flex project (Flex 2.0.1 hotfix 2) and I am rookie in Flex programming. So, I wrote code for accessing some ASP.NET web service:

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

    [Bindable]
    public var users:ArrayOfUser;

    private function buttonClicked():void
    {
        mx.controls.Alert.show(dataService.wsdl);
        dataService.UserGetAll.send();/
    }

    public function dataHandler(event:ResultEvent):void
    {
        Alert.show("alo");
        var response:ResponseUsers = event.result as ResponseUsers;
        if (response.responseCode != ResponseCodes.SUCCESS)
        {
            mx.controls.Alert.show("Error: " + response.responseCode.toString());
            return;
        }
        users = response.users;

    }

]]>

<mx:Button label="Click me!" click="buttonClicked()"/>

And this is what I get from debugger:

And finally I get this error "Error #1006: getAttributeByQName is not a function.". As you can see, I get correct response from web service, but dataHandler function is never got called.

Can anyone please help me out?

By installing Hotfix 3 I solved the problem as it never existed.
