When you create a delegate, you need specify which method on which
object should be called.
So in this case, the object is the canvas and the method is "test2".
//create the delegate
if ( typeof delete_button.del == "undefined" ) {
delete_button.del = new LzDelegate( *canvas*, "test2");
}
Why does it have to be defined "on" the button, it's defined in the
source, which you can view here. Thanks for your time.

buildoutbuilder.lzx is the file you're looking for.
Thanks again!

Ken
