Instantiating one CFC twice

When I try to instantiate one CFC from 2 different CFCs, ColdFusion returns a 500 error. I tried making one of the CFC extend the other, but it did not solve the issue. Is this possible, or am I simply doing something incorrectly?

<!--- one.cfc --->
<cfcomponent name="FirstCFC">
   <cfset this.Tools = createObject('component', 'toolbox').init()>
....
</cfcomponent>

<!--- two.cfc --->
<cfcomponent name="SecondFC">
   <cfset this.Tools = createObject('component', 'toolbox').init()>
....
</cfcomponent>

<!--- toolbox.cfc --->
<cfcomponent name="Toolbox">
   <cffunction name="init" access="public">
      <cfreturn this>
   </cffunction>

   <cffunction name="someFunc" access="public">
   </cffunction>
</cfcomponent>

Here is a screenshot of the 500 error

Solution

  • The java stack trace you've included is indicitive of an infinite recursion error. Take care when creating objects of type A, which have a new object of type B in their pseudo-constructor. If the object B itself creates an object of type A in its pseudo-constructor, you have yourself an infinite recursion of objects being created, ending in an ugly java stack trace.
