Question

Again pulling my hair out due to some Flex/AS3 weirdness. The following code does not compile due to error 1120 – Access of undefined property AbstractWizardModel

<mx:HBox id="cntr_buttons" width="100%" horizontalAlign="right">
   <mx:Button label="{model.getButtonLabel(AbstractWizardModel.GO_BACK)}" />
</mx:HBox>

The constant is defined (in AbstractWizardModel) as:

[Bindable]
public class AbstractWizardModel extends EventDispatcher
{
   public static const GO_BACK : String = "goBack";
   ...
}

Replacing ‘AbstractWizardModel.GO_BACK’ with ‘”goBack”‘ does the trick, but what was the problem?

Thanks!

PS: Of course I am importing the AbstractWizardModel in the MXML code

Answer 1

Oh man this is so weird..

I found kind of a solution, thanks to all comments, which helped me to get on the right track, but still think this is a bug in Flex.

First of all I have to add that (in my code) the MXML and AbstractWizardModel class are in the same package.

The ‘getButtonLabel()’ function that I am calling is declared as

[Bindable(event="getButtonLabelChanged")]
public function getButtonLabel (buttonId:String) : String
{
    ..
}

If I remove that [Bindable..] annotation, the code compiles.

If I leave it there, I have to add an import for class AbstractWizardModel, although it is in the same package. Anyway, that fixes the problem, too.

However 🙂 FB4 removes that import everytime it organizes imports, so that user comment was helpful too.

Happy to hear your thoughts!
