[flexcoders] Data binding warning

[julien castelain]

Hi list,

I have a model object in my flex application that has a public
"connected" (Boolean) property like this:

public class Model {
   [Bindable]
   public var connected:Boolean = false;
   ...
}

In my mxml file i have an instance of that model:

[Bindable]
private var _model:Model = Model.getInstance();


When i compile, even though every thing works as it should i have this
warning: 

Data binding will not be able to detect assignments to "_model".
source="{_model.connected}"

So, should i care about that warning, and is there a solution to solve
this? Thanks
