Correction: the <cfswitch
expression="#GetToken(attributes.fuseaction,2,'.')#> requires a prefix. So
you would need to change the <cfswitch> if you're using it in a nested
environment.

Subject: Nested fuseboxes
A while back, someone asked about nesting fuseboxes and we had some
discussion on that. I'm working on a book for Prentice Hall and in playing
around with some sample code for it, I thought of something that might be
helpful. I'm going to test it out to see if I like it, and thought you all
might like to evaluate it.
Here's a quote from the forthcoming book:
The other approach to nested fuseboxes relies on using an abbreviated prefix
to help the main fusebox identify who the fuseaction belongs to. If I am
working in the UserManger fusebox, I might give all my fuseactions a prefix
of UM with a separator:
UM.loginUser
UM_validateUser
In the main fusebox, you then change your <cfswitch> statement so that,
instead of looking for attributes.fuseaction, it looks for a prefix:
<cfswitch expression = "#GetToken(attributes.fuseaction,1,'.')#">
Your <cfcase> statements now only need send the action to the appropriate
nested fusebox:
<cfcase value="UM">
<cfinclude template="UM/index.cfm">
</cfcase>
The last thing to do is to code the nested fusebox so that it strips away
the prefix.
<cfswitch expression = "#GetToken(attributes.fuseaction,2,'.')#">
The nice thing about this system is that it works whether you have prefixes
or not.
<cfset myName = "hal.helms">
#GetToken(myName,1,'.')#
#GetToken(myName,2,'.')#
<cfset myName = "hal">
#GetToken(myName,1,'.')#
#GetToken(myName,2,'.')#
will both return "hal"
