Explanation
When a user interacts with a JavaBean at run time, it usually causes an event to occur. You can use FBEAN.ENABLE_EVENT to register a listener for the event, so that when the event occurs Forms will fire the When-Custom-Item-Event trigger. In this trigger, you can code a response to the event. The :SYSTEM.CUSTOM_ITEM_EVENT and SYSTEM.CUSTOM_EVENT_PARAMETERS variables contain the name of the event and information the bean is sending to the form.
