Fairly simple question.  Lets say I have a hunk of code stored in a table.  I get said code chunk via a cfc, returning a query string to the page.  I access the chunk like so: <cfoutput>#queryName.codeChunk#</cfoutput>.  The code is output as it should be, but the coldfusion variables are not rendered.  What must I do to output the code WITH rendered codlfusion variables (that lie within the code chunk)?

In the end code such as this:

     templateBG = new Image();
     templateBG.src = "http://#cgi.http_host#/userfiles/#application.clientId#/templates/#this.template#/template_#this.template#_01.png";

and this:

     <img src="http://#cgi.http_host#/userfiles/#application.clientId#/templates/#this.template#/template_#this.template#_01.png">

...should be rendered with rendered variables.

Try using the evaluate() function. It should force an evaluation of the CF variables within the string.

Tried that already...  :(

 Invalid CFML construct found on line 1 at column 1.
ColdFusion was looking at the following text: <

It doesn't make it past the first character (since it's a tag).  If it were plain text with variables, that would work.

Can you give a _small_ example of exactly what #queryName.codeChunk# looks like?

So #queryName.codeChunk# contains that entire block of code above? I wasn't sure because it contains </cfoutput> tags too.

You could dynamically create a temporary file on the fly, and then cfinclude it back in.

<cffile action = "write"
   file = "tmpFile.cfm"
   output = "#queryName.codeChunk#">

<cfinclude template="tmpFile.cfm">

To add to that idea, if you're using CF9 you could try doing that with the VFS/RAM Disk capability that was introduced.

I did what you suggested. (before you suggested it)  ;)  Only with a twist...
<div>
	<ul>
		<cfloop query="getEmailTemplates">
			<cfset request.templateData = application.template.getTemplate(templateID=#getEmailTemplates.layoutID#)>
			<cfset request.tempFileName = "/admin/" & request.thisModule & "/template." & numberFormat(getEmailTemplates.layoutID, "00000") & ".cfm">
			<cfset request.tempFileFullPath = "/var/www/shared.emtoobox.com/htdocs" & request.tempFileName>
			<cfset fileWrite(request.tempFileFullPath, request.templateData.html)>
			<li style=" list-style: none; display: inline; ">
				<img src="http://#cgi.http_host#/userfiles/#application.clientId#/templates/#numberFormat(getEmailTemplates.layoutID, "00000")#/preview.png" onclick="ColdFusion.navigate('#request.tempFileName#','ajaxContainer')" width="75" />
			</li>
		</cfloop>
	</ul>
</div>

<cfdiv id="ajaxContainer"></cfdiv>
