Controlling process flow using events

* New for 9.5 *

The LiveCycle ES2.5 server provides an event framework that enables business events to be defined. Events provide processes with a mechanism for interacting with the event framework.

Events are represented on process diagrams as circle-shaped icons. Routes can be drawn from events to other elements on the process diagram so that the occurrence of the event alters the progression of the process.

You can use Asynchronous, Timer, and Exception events types. Each event type is either a service-defined event or a custom event. When adding a custom event to a process diagram, select an event that is located in the current application or in another application. The other application can be either local or remote. To use custom events from remote applications, the applications must be deployed on the LiveCycle server.

Processes can receive notifications about events that occur during process execution. You can configure the conditions to respond to for each notification you receive. Processes can throw events to provide notifications to other processes about an occurrence in the process. As part of sending a notification, you can send specific details about the event or include additional data.

You can also use events to catch errors that occur on the server upon process execution, handle situational errors, and to insert time-based execution constraints on operations. Events can also be used to pass information from process to process using a pre-defined data schema.
