I moved the >>with: to the end of the cascade, and I removed the >>onClick:,
but that didn’t seem to make a difference. The Transcript printing in my
callback: was never executed.

I had been looking at examples before I got to this point, but I must not be
looking at the correct ones. Are you referring to any of the following, or are
there other examples that you would suggest?

JQFormFunctionalTest>>renderCheckBoxOn:
JQFormFunctionalTest>>renderMultiSelectListOn:

JQButtonFunctionalTest>>renderCheckBoxOn:

Scriptaculous.SUFormTest>>renderCheckBoxOn:
Scriptaculous.SUFormTest>>renderMultiSelectListOn
