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

The error is about the class AbstractWizardModel, not about the constant GO_BACK. You need to have an import statement for the class inside the mxml file:
before you can use the class. EDIT: replace "the.package." with whatever package the class is in.
