Thanks Dan, Sean, To take this a step further now, if you are mixing in a function into other CFCs (by reference), and that function has code to set variables.xyz=123, will that variable be stored in the proper CFC? Are there any threading issues or potential conflicts with doing this if had, say, 100 objects all sharing this function by reference?
