Stephen,
I just looked at your code again - and noticed that although you are
providing an "execute" function, you are not calling it. So your
makeChildWidgets is never getting called.
So, further to my last suggestion I think you should do the following in
your render():
this.execute();
var domNode = this.document.createElement("div");
this.domNodes.push(domNode);
parent.insertBefore(domNode,nextSibling);
this.renderChildren(domNode,null);
This is a pretty standard pattern per the core widgets.
Chris.
