Yes, I understand what you are saying. I have several models. They all
behave correctly and this one only creates a new instance every time.
I have changed my code to look like other models:
package
{
import com.adobe.cairngorm.model.IModelLocator;
import flash.events.EventDispatcher;
[Bindable]
public class ModelLocator extends EventDispatcher implements IModelLocator
{
private static var _instance:ModelLocator;
public function ModelLocator(enforcer:SingletonEnforcer)
{
if (enforcer == null){
throw new Error("You can have only one ModelLocator");
}
}
public static function getInstance():ModelLocator{
if (_instance == null){
_instance = new ModelLocator(new SingletonEnforcer());
}
return _instance;
}
}
}
class SingletonEnforcer{}
