Even when the CFC is recompiled through instantiation of another instance of it, the existing instances' behaviour remains untouched.
In Java, this is NOT the way it works, because an object only houses instance data (state), and all methods and static variables reside in the class, which is read from disk once, and stored for use by ALL instance of the class. I'd definitely say this is a bug. CFC's have no runtime awareness of their superclasses, because their functionality is aggregated when instantiated. I don't know how it works, but I bet it similar to renaming functions by assignment. Thus, you have an in-memory representation of the function, rather than a pointer to a class-definition that has a single representation of the function when you have an inherited method. That would create the situation where cached CFC instances don't change behaviour when their class changes. barneyb --- Barney Boisvert, Senior Development Engineer AudienceCentral (formerly PIER System, Inc.)
