Why is ColdFusion giving me grief over this code?

Can be done natively in CF with two lines of code:
request.args = url;
StructAppend(request.args, form);
Et voila

Yes...
StructKeyExists is better in most cases.
Thanks, everyone, for clearing that up.
On a side note... is it better to use
'structKeyExists(url, 'property_type')'
as opposed to
'isdefined('url.property_type')'
???
And, if so, why?
Thanks,
Rick

===========================================
The answer is a resounding "depends". It depends on:
1) Version of Coldfusion
2) Whether or not the variable exists.
3) How many variables are in the url scope.
My main beef with isdefined is that it scope hunts and if the variable
is not defined it may take longer to return false. Structkeyexists is a
bit more verbose about what you are looking for. The fact of the matter
is you are talking a difference of milliseconds. I have measured a
difference before, but I had to loop thousands of times for it to add up
and that isn't a very reliable test to compare a production app against.
Here's the general consensus on this kind of stuff: Code what is the
easiest to read and maintain. If you have a performance problem with
the code, address it at that time.

I did not look at the function but out of curiosity why not just use the
StructAppend() built into CF? I often copy the URL scope into the Form on
some of our pages due to not know if a value will be passed in by one or the
other. So I just put in a <cfset StructAppend(FORM, URL, false) /> for
those needs.

I have a function that does that. It is pretty old so don't make fun of
me..... but it works ;)

Steve Nelson had a tag formurl2attributes.cfm
I can't seem to find it for download though.

as a followup... here's that custom tag.

The whole <cfswitch...> tag can be, but not just the first half.
I.E.
<cfif...
<cfswittch>...</cfswitch>
<cfelse>
<cfswitch>...</cfswitch>
</crif>
Allowed.
<cfif...
<cfswittch>
<cfelse>
<cfswitch>
</crif>
</cfswitch>
Not Allowed.
The quikest fix to what you are trying to do would be.
<cfswitch
expression(#iif(isDefined('url.property_type',de(url.property_type),de(form.property_type))#)
But this is they type of solution the usually quickly gets re-factored
into cleaner and simpler code.

not like that, no. you need to finish the switch inside of each condition.
would be "better" to do:
<cfif structKeyExists(url, 'property_type')>
<cfset variables.property_type = URL.property_type />
</cfif>
<cfif structKeyExists(form, 'property_type')>
<cfset variables.property_type = form.property_type />
</cfif>
then
<cfswitch expression="#variables.property_type#">
(case statements)
</cfswitch>
i think there's a custom tag out there that will automagically put
form/URL vars into an "attributes" scope. This is how fusebox does it
by default (and in Model-Glue it's in the 'event')... but I seem to
recall a custom tag that would accomplish the same end for folks who
aren't using a framework.

You need to have a closing cfswitch containing cfcases for it to work.

?
<cfif isdefined('url.property_type')>
<cfswitch expression='#url.property_type#'>
<cfelse>
<cfswitch expression='#form.property_type#'>
</cfif>
It's complaining with this error:
Context validation error for the cfelse tag.
The tag must be nested inside a CFIF tag.
Can cfswitch tags not be nested inside cfif tags?
