I am not getting the changeHeight event fired. I have a completely stripped
down class that is subclassed from a composite container and all it has is
an event listener for changeHeight and one for appear. The appear event is
firing just fine, but the changeHeight event never fires. I did a
Playground test, and that works fine, but in my app, it doesnt work. Here
is the simple class that is not working:

qx.Class.define("swep.J.sfIMBaseGrid",
{
  extend : qx.ui.container.Composite,
  construct : function()
  {
    this.base(arguments);
    this.setLayout(new qx.ui.layout.Canvas());
    this.addListener('changeHeight', function(evt){
      this.info(evt.getData());
    }, this);
    this.addListener('appear', function(){
      this.info('got the appear event');
    }, this);
  }
});

(this code was hand entered so if there is a syntax error it is not in the
actual code)

If I create the control, add it to getRoot() of my application, the appear
event fires, and when I change it's height, that event doesn't change.

I even tried to create a qx.ui.container.Composite and do the same thing
manually and the event doesn't fire. What can be stopping the changeHeight
event from firing?

Here is the Playground test I did that shows it working correctly: *
