Note: this is just a simplized example of what i'm trying to do to get the idea across.

The problem I'm having is that I want to use cfinclude inside cfcomponent so that i can group like methods into separate files for more manageability. The problem I'm running into is when i try to extend another component that also uses cfinclude to manage it's method as demostrated below. Note that ComponentA extends ComponentB:

ComponentA
==========
<cfcomponent output="false" extends="componentb">
    <cfinclude template="componenta/methods.cfm">
</cfcomponent>

componenta/methods.cfm
======================
<cffunction name="a"><cfreturn "componenta-a"></cffunction>
<cffunction name="b"><cfreturn "componenta-b"></cffunction>
<cffunction name="c"><cfreturn "componenta-c"></cffunction>
<cffunction name="d"><cfreturn super.a()></cffunction>

ComponentB
==========
<cfcomponent output="false">
    <cfinclude template="componentb/methods.cfm">
</cfcomponent>

componentb/methods.cfm
======================
<cffunction name="a"><cfreturn "componentb-a"></cffunction>
<cffunction name="b"><cfreturn "componentb-b"></cffunction>
<cffunction name="c"><cfreturn "componentb-c"></cffunction>

The issue is that when i try to initialize ComponentA I get an the error: "Routines cannot be declared more than once. The routine a has been declared twice in different templates."

The whole reason for this is because when you use cfinclude it's evaluated at RUN TIME instead of COMPILE TIME.

Short of moving the methods into the components themselves and eliminating the use of cfinclude, how can i get around this or does someone have a better idea splitting up large components?
