I'll settle with the one in almost a billion (1,999999999) change that
they'll duplicate (well, scaled down with each subsequent call).
If anybody gets a conflict....well, they're a lucky fool.

I was originally using #request.tapi.uName()# which I still use for
generating ID's for stuff that's going to go into my database, but
seemed a bit inefficient for these ultimately given the volume of html
elements on a page and the fact that they're transient (most of the
time you won't be storing these in your db or anything). So in order
to make them a bit faster I created a separate
#request.tapi.serialize()# function which produces a mostly numeric
result with a non-fixed number of digits. My algorithm was (iirc)
"tap_"
& dateformat(now(),"yyyymmdd")
& timeformat(now(),"HHmmss")
& gettickcount()
& randrange(1,999999999)
I'd have left it at getTickCount() except that you can get several
calls to the function per milisecond. The remaining bits leading up to
the current year help to ensure that if the resulting html code gets
coppied into a flat html template somewhere else, the likelyhood of
having a duplicated id in the html is minimalized, since any duplicate
would likely have to have been created by the same system during the
same calendar second and with the CF Server running for the exact same
number of miliseconds prior to the function call. heh :)
