Hi Brendan,
Good point, as always. I was only dealing with the mechanical issue of
being able to send runtime values into the web event.
I recall that everything is well-documented. The vanilla handlers call
doAction, and the exact code that is executed on behalf of each handler is
to be found in the javadoc. The point is made that doAction is just a
4GLish shortcut, and that developers should substitute modified versions of
the vanilla code, as needed.
