Yep, that's indeed a possible cause. To be clear, this is why my last point asserted that a test should involve confirming that no application.cfm code was influencing things. There can be lots of possible explanations. Once that proved it was the problem, it would be more obvious then that he'd need to look at the application.cfm/cfc that was influencing things.

Sometimes people choose to make their form vars and their url vars combined so they only have to check one... just a thought.

First, to be clear, I tested it on CF8 (8.0.1) and did not experience it. Let's confirm: are you on 8 or 8.0.1, just in case that may make a difference. But I suspect it's something else. Second, are you saying that if you run the code right now (on your server), you still have the problem? Third, how about this: if you drop it into a new template that has no code other than this, does it still happen? Finally, if you put that file into a new directory with a blank application.cfm (so that you're not inheriting any other), does it still happen? As I tell people all the time when they bring me in to consult on solving CF troubleshooting problems (big or small), there is always an explanation-it just isn't always what it seems at first. /charlie From: [email protected] [mailto:[email protected]] On Behalf Of Dusty Hale Sent: Wednesday, July 14, 2010 2:02 AM To: [email protected] Subject: Re: [ACFUG Discuss] disappearing variable values I've had a similar thing with url variable: <cfparam name="url.myvariable" default="The Sky is Blue"> <cfparam name="url.donorid" default="Roses Are Red"> <p>The value of url.myvariable is: <cfoutput>#url.myvariable#</cfoutput></p> <p>The value of url.donorid is: <cfoutput>#url.donorid#</cfoutput></p> <cfif url.donorid is ""><p>It's Empty</p></cfif> <cfabort> For some reason url.donorid always disappears unless there is an actual passed variable in the url. However, in theory the cfparam tag should set the default if none in the url. But no. It comes out an empty string. Here's the really strange thing because it seems to be just the variable name "donorid" and if I change the name then no problem. I'm on CF8 and this little quirk drove me nuts in an application trying to figure out why. On Tue, Jun 22, 2010 at 5:23 PM, Troy Jones <[email protected]> wrote: I am having a perplexing issue. Has anyone ever had an instance where it seemed as if a variable just "poofs" into thin air? For example, when I run the following code: <cfdump var="#attributes#"> <cfdump var="#pageID#"> <cfdump var="#thisPage#"> <cfset testVar = thisPage.form_id> <cfoutput>thisPage.form_id = #testVar#</cfoutput> <cfif attributes.mode is "do"> <cfset thisForm = application.com.lib.getData("vformfields","form_id = #testVar#","field_sortorder")> The variable "testVar" exists up until the setting of "thisForm" which I've verified with the <cfdumps>. At that point, when #testVar# is called, it is passing a NULL value to the SQL statement and throwing an error. I've tried recreating the error with a standard <cfquery> tag just to see if something was getting jacked up in the function call, but it had the same result. It's as if the value just ran away and left. I've never seen anything quite like it and have run out of tails to chase, so to speak. This is on CF9 Enterprise, for anyone who needs it and any help would be greatly appreciated.
