Greetings,
Very nifty Lee. I'm in the process of putting together a FB3 site at the
moment and this will come in rather handy.
Thanks!

Just mucking around while re-architecting a small app still in FB3.
Built myself a little old-fashioned Custom Tag "cf_include". Probably
others have built similar things before. Would obviously be easy to
implement in FB4+ engines too.
Anyway, here is a sample chunk of fbx_switch code:
<cfcase value="User_Start_ACTION,default">
<cfset xfa.onSuccess="vacancies.User_ID_FORM"/>
<cfset xfa.onPositionNonexistent="vacancies.Error_page"/>
<cfset xfa.onPositionClosed="vacancies.Error_page"/>
<cf_include template="sel_position.cfm">
Input:
positionID: attributes.number
Output:
position: recordset
</cf_include>
<cf_include template="in_userid.cfm">
Input:
position: recordset
Output:
fuseaction: attributes.string
positionID: attributes.integer
userID: attributes.string
Responsibilities:
If the Position recordset is non-empty, show a form for
capturing the User's ID
</cf_include>
<cfset request.page.subtitle="User Start - ACTION"/>
</cfcase>
And here is the custom tag, cf_include:
<CFIF thisTag.ExecutionMode is 'end'>
<CFTRY>
<CFINCLUDE TEMPLATE="#attributes.template#">
<CFSET thisTag.GeneratedContent = "">
<CFCATCH TYPE="MissingInclude">
<CFSET thisTag.GeneratedContent = "<p><table border=1
cellpadding=10 cellspacing=0
width=75%><tr><td><h4>#attributes.template#</h4>#htmlcodeformat(thisTag.generatedContent)#</td></tr></table>">
</CFCATCH>
</CFTRY>
</CFIF>
Now you can run the application. If the required template exists, it
is cfincluded as usual. If it does not exist, then the template name
and enclosed description/specification are displayed. With a bit of
tweaking, the cf_include tag can display any error down at the fuse
level side-by-side with the fuse's specification, which could be very
handy.
Anyways, just a trivial little thing to amuse myself when the
air-conditioning is too hot for real work...
See ya,
LeeBB
