gwt-exporter: Exporting interfaces

I have a project in GWT that I am trying to export to javascript using GWT-exporter. The problem is that I have an interface which I need to export and have the client provide implementations for the methods. For example:

@Export

public interface Listener extends Exportable{
    public void method1();

    public void method2();
}

Could somebody please help me with this? If I can't export this, how should I go about solving this problem? I don't know much javascript, so any suggestions will help. Thanks!!

You can export an interface and export methods using it, but you cannot instantate an object of it from js unless you export a class as well. If you want to provide the implementation of the mehod using a js function you have to use the @ExportClosure annotation.
