Thanks Bob,
The explanation makes sense, and as a matter of fact that's what I've
always done in the past whenever I needed to pass JS back to the CF server,
unfortunately on this particular app, for reasons which would take WAY too
long to explain I can't use that method.
I ended up finding a workaround to my particular problem, but it
would still be cool to know if anyone has ever been able to successful pass
JS to the CFSERVER through WDDX.
I guess you wouldn't really be able to get around some kind of
submit back to CF on the server side. Anyway, thanks for the help Bob. :-)
