tracker issue : CF-3418667

Problem Description:

a cfc method used as a callback function from another cfc uses the variables scope of chte calling cfc instead of the callee.

Problem occurs the same way in CF 10 wher function coudl be used as a type declarator


Steps to Reproduce:

component  MCU {
  variables.mcu.clock = 0;
 //  more of variables.mcu.*

  Init () {
//    Create all targets, call each target’s registerMCUListener to let them know whom to call back.
               variables.mcu.targets[i] = CreateObject ("component", "target").Init ();
               variables.mcu.targets[i].registerMCUListener (cbFromTarget);
  }



   private numeric function cbFromTarget (struct msg) {

writedump (var=#variables#);  // This shows the variables scope of TARGET, expected MCU  <<<<<<<<

      variables.mcu.events.list[variables.mcu.events.ptr] = {
                                                                clock = variables.mcu.clock,
                                                                msg = arguments.msg
                                                             };
      return 0;
   }
}
---


---
component TARGET {
  variables.tg.clock = 0;
  // more of variables.tg.*


   public void function registerMCUListener (any mculistener) {
      /*
       * register the mcu listener function to notify of any events
       */
      variables.tg.mcu.listener = arguments.mculistener;
   }

   private void function ToMCU (struct msg) {
      /*
       * register the mcu listener function to notify of any events
       */
      if (isCustomFunction (variables.tg.mcu.listener)) {
         variables.tg.mcu.listener (msg);
      }
   }
}
---


Idea: The cbFunc registers the message in the MCU’s variables scope 

But it does not. The marked variables.mcu.clock is throwing an error because mcu.clock does not exist in the variables scope.

Observation: CF is using the variables scope of TARGET instead of MCU therefore no clock.

I confirmed that by dumping the variables scope just before that line marked with <<<<<<<<<



Actual Result:

line marked with <<<<<<<< shows the variables of TARGET

Expected Result:

variables of MCU


Any Workarounds:

None, because BOTH cfcs use cb to communicate with each other and other cfcs
