<!--- super.cfc --->
<cfcomponent name="Super">
<cffunction name="functionA()" returntype="string">
<cfreturn functionB()>
</cffunction>
</cfcomponent>
<!--- sub.cfc --->
<cfcomponent name="Sub" extends="Super">
<cffunction name="functionB()" returntype="string" access="public">
<cfreturn "Hello, World">
</cffunction>
</cfcomponent>
<!--- test1.cfm --->
<cfset super = createObject("Component", "Super")>
<cfoutput>#super.functionA()#</cfoutput>
<!--- test2.cfm --->
<cfset super = createObject("Component", "Super")>
<cfoutput>#super.functionB()#</cfoutput>
Neither of these tests should work. They didn't work for me.
A supertype should not need to call a function in a subtype. If that's
really the case you should "pull up" the function from the subtype to
the supertype.
This will work:
<!--- super.cfc --->
<cfcomponent name="Super">
<cffunction name="functionA()" returntype="string">
<cfreturn functionB()>
</cffunction>
<cffunction name="functionB()" returntype="string" access="public">
<cfreturn "Hello, World">
</cffunction>
</cfcomponent>
<!--- sub.cfc --->
<cfcomponent name="Sub" extends="Super">
<cffunction name="functionC()" returntype="string" access="public">
<!--- since I extend Super I inherit functionB() and can use it --->
<cfreturn functionB()>
</cffunction>
</cfcomponent>
