Question

I’ve got a model class with custom change events, which is working fine if I make a reference to that class in my mxml using;

[Bindable] private var firstClass:FirstClass;

The objects gets filled by a server side script, so don’t worry, firstClass isn’t null.

Anyhow, accessing firstClasses properties in mxml works perfectly fine using curly brackets. The binding works just as expected.
However, is there any way to access firstClasses properties and set them to say a label with pure Actionscript.

lblTest.text = firstClass.property;

The code above doesn’t work. I suppose because it sets a fixed value to the label.
I’m aware of using BindingUtils.bindProperty to explicitly set the source and destination for the binding. However, this turned out to cause huge performance issues in my (mobile) application.
So is there a simpler, more efficient way to do this?

No. The BindingUtils uses propertyChanged events to detects when an object’s property changes. You won’t be able to bind something without listening to events, and the most painless way to do it is using BindingUtils.
