CFCATCH throwing error in CFC - coldfusion

Question

For some reason, a piece of code that works fine on a *.cfm page, and did work fine in a *.cfc, now is throwing an error when error is detected.
The error is:
Element SQL is undefined in CFCATCH.
The code block where this is getting throw looks like this:
<cfcatch type="database">
<cfset errorMessage = "
<p>#cfcatch.message#</p>
<p>Please send the following to a developer:</p>
<p>#cfcatch.SQL#</p> <--- ERROR HERE
<p>#cfcatch.queryError#</p>
<p>#cfcatch.Where#</p>">
some other stuff
</cfcatch>
Any thoughts?
UPDATE
Using #BenKoshy suggestion, I modified my <cfcatch> statement.
Remember K.I.S.S.? Keep It Simple Stupid
Using his method and then modifying it, I was getting more data back than I was going use, so I went with a simple version, and it works as advertised.
<cfif isDefined("cfcatch.message")>
<cfset errorMessage = errorMessage & "<p>#cfcatch.message#</p>">
</cfif>
<cfif isDefined("cfcatch.SQL")>
<cfset errorMessage = errorMessage & "<p>Please send the following to a developer:</p><p>#cfcatch.SQL#</p>">
</cfif>
<cfif isDefined("cfcatch.QueryError")>
<cfset errorMessage = errorMessage & "<p>#cfcatch.queryError#</p>">
</cfif>
<cfif isDefined("cfcatch.Where")>
<cfset errorMessage = errorMessage & "<p>#cfcatch.Where#</p>">
</cfif>
Nice and easy and it works. KISS

Answer 1

Just means the error data did not contain an SQL statement. Shouldn't assume that variable will exist for all errors:
<cfif isDefined("cfcatch.sql")>
<p>#cfcatch.SQL#</p>
</cfif>
Is the easy fix. Probably best to loop through the struct like this:
<cfparam name="errorMessage" default="">
<cfloop collection="#cfcatch#" item="this">
<cfset errorMessage = errorMessage & "<p>#cfcatch[this]#</p>">
</cfloop>
