Gnosis Workflow, EventHandler-type Views, and Expression properties can be triggered to handle custom Events.

EventHander-type Views must be of gsAction format.

EventHandler Expression properties must contain an Anonymous Function.

Since derived Item Types automatically inherit properties, this approach allows for logical inheritance of Events. Derived Item Types can override the Expression Property and use the $Base variable to call the base Item Type Expression.

Custom Events are fired using the FireEvent function.
