The ui.Interface.refresh method is possibly one of the most misused pieces of Genero code. A key point about the Genero architecture is that there are two components, the runtime or back-end, and the front-end, that communicate backwards and forwards across the network. The runtime sends to the front-end any user interface changes but the runtime only does this when it is expecting a response back from the user. The ui.interface.refresh method allows these changes to be sent when the runtime is not expecting a response back from the user. This is necessary for cases such as messages and user interfaces that display the progress of a long running batch process. However doing so increases the network traffic between the runtime and front-end, so its use will typically be controlled so that the screen is not updated faster than the end user can read it.
The article introduces the method, illustrates a few cases where it is ok to use, and a common case we see where it should not be used.
