The CSAF allows the user to register and receive notifications when certain events occur. Currently, three persistence events are supported: objectDeleted, objectCreated, objectUpdated. These events can be intercepted by implementing the interface com.softwareag.centrasite.appl.framework.persistence.PersistenceEventListener. Such listeners are registered via the BeanPool, which has methods for adding, removing and retrieving listeners.

All of the supported events are post events; in other words, they are fired after an action has been performed.

Using CSAF in pre-action events has some limitations. This is because the CSAF tries to establish its own connection to the registry data. Under certain circumstances, it may happen that a user searches the registry for a transient object (for example, an object which is still not persisted into the database) and, on which a pre-action event is executing; in such case the user may not be able to retrieve the transient object created using another connection. As a best practice, we recommend that you use the JAXR-based API connection for any pre-action events.
