In this example, the ‘data’ property is an Object. Properties assigned to
Objects are not bindable. There should have been warnings in the compile
output or in the console at runtime.
If you know the set of properties on the data object, you should define a
class for that.
[Bindable]
public class MyModelDataSubObject
{
public var propOnData:String;
}
And:
[Bindable]
public class ModelLocator extends EventDispatcher implements IModelLocator
{
private static var _instance:ModelLocator;
public var data:MyModelDataSubObject;
public function ModelLocator(enforcer:SingletonEnforcer)
..
