The key to me was setting that var as bindable and using the
HTTPUtil class to retrieve the value from the parameters on the
html (owner) page's url. Then the creationComplete() function
actually does some work
before doing the HTTPService.send().
Thanks for taking the time to reply. I've posted a few things
(that I don't see totally out of the ordinary), and it seems to be
a bit of a "cold" forum at times. :(
