Aw: Re: Emulating Java Reflection with deferred binding

Ah its also missing a default return value in your generated method:

public <T extends Constructable> T instantiate (String className) {

  if("MyPanel".equals(className)) {

     return (T) new MyPanel();

  }

  .....

  if("MyPanel2".equals(className)) {

     return (T) new MyPanel2();

  }

  ....

  return null; // no matches

}

You can also always add the "-gen <path/to/output/folder>" option to your compiler args / run configuration. That way GWT will save all generated sources in your specified folder and you can actually see what has been generated.
