did you put quotation marks around the var name inside the IsDefined()
function?
e.g. <CFOUTPUT>#IsDefined("var")#</CFOUTPUT>

Subject: Re: "isdefined" obsolete?
Sorry to contadict you Adrian, but I can say with complete conviction
(and no explanation at all) that these experiences did happen...I know that
obviously a variable either exists or doesn't. That
doesn't mean that in every instance a function will work though. I replaced
the isdefined function (after checking to be sure the
syntax was correct) with parameterexists and it worked. I switched it back
to isdefined and it did not. I did it in more than one
instance and I confirmed the issue and verified the results of the
workaround with other cf programmers on site.
Why would I say the problem did arise and have such a simple a workaround
if it was a figment of my imagination or some other
underlying issue totally seperate from the cf function? I do not remember
what version of CFAS or on what platform it was running
(I do know it wasn't 4.5x. I also no longer have the exact pages where I had
the issue off the top of my head. I have been
programming in cf for 5 years now so the jobsites where the pages reside are
not necessarily available to me now.... anyway I
replaced the isdefined function on them anyway so I couldn't find them even
if I had access. All I am saying is that you cannot
tell me what happened or that it could't without working on the applications
I did in the environment I was working in.
I always say "if it doesn't work do what it takes to corrrect it" In this
case I did not get stuck on the fact that the problem
was totally illogical. I simply made it work. In this case it was as simple
as a change of function.
I have seen postings up here for issues that should never have come up
logically speaking yet they do. I would think it is more
productive to say "that is an interesting issue...how did it happen" in any
of these cases. Than to say "that can't happen
because...." Whenever I try that one on the users of applications I have
worked on I am reminded that I do not have all the
answers.
sorry about the typo I hope I won't be graded on it ;-)
