Hi Steven,
You could try using arguments.caller to check if the setter was called by
the controller. Here's a little test function I whipped up on the _root:
function testCaller(){
trace (typeof arguments.caller)
trace (arguments.caller == controller.test)
trace (arguments.caller == notcontroller.test)
}
controller = new Object();
controller.test = function (){
_root.testCaller()
}
notcontroller = new Object();
notcontroller.test = function (){
_root.testCaller()
}
The output is:
function
true
false
function
false
true
This gives you a way to check if the function was called from the controller
or the notcontroller.
The downside is that this checks for a specific function within a
controller, not just any controller function. I wonder if there's a way
around it?
