I think you are misunderstanding delegate:
http://labs.openlaszlo.org/trunk-nightly/docs/reference/LzDelegate.html
If test2 is a method on the canvas and you want to invoke it when
button is clicked, you would say:
new LzDelegate(canvas, 'test2', delete_button, "onclick")

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.
http://github.com/xkenneth/buildoutbuilder/tree/master/buildoutbuilder.laszlo/src
buildoutbuilder.lzx is the file you're looking for.
Thanks again!

Do you have a "test2" method defined on button? It would seem to me
that you don't, because you're instantiating
it right there, and there is no test2 method defined in the lz button
component class, that I know of..

All,
Here's the error: ERROR @lz/button.lzx#35: Invalid delegate:

You can call a method on another object, using a delegate, but
you'd
have to create the delegate to point to your object
e.g.,
new LzDelegate(yourinstance, "test2")
Your delegate was created to call the test2 method on your button
instance.

What is the error? Your test2 method is never getting called?
Where is
the "test2" method being declared on
the button class? Don't you need a subclass of button, in order to
define your method on it?
