So that means that Mach-II is based on the singleton pattern then! Regards Andrew Scott Technical Consultant

This is essentially how it works: 1. Created a central method called "getSingleton" that manages the creation and retrieval of singletons. any getSingleton(string componentPath) 2. The getSingleton method checks to see if a key matching the componentPath exists within a struct stored in application scope. a) If the key doesn't exist, then a new key is inserted into the struct, and its value is the instantiated component (with appropriate locking). b) The persistent instance of the component is returned. That is essentially how it works.
