* CRUD events. If a CRUD event occurs it will send a signal to the model
|
|
* that belongs to the CRUD bean and this model will take over control from
|
|
* there. This method will attach the following event listeners to the observable:
|
|
*
|
|
* - 'update' (gets called by R::store, before the records gets inserted / updated)
|
|
* - 'after_update' (gets called by R::store, after the records have been inserted / updated)
|
|
* - 'open' (gets called by R::load, after the record has been retrieved)
|
|
* - 'delete' (gets called by R::trash, before deletion of record)
|
|
* - 'after_delete' (gets called by R::trash, after deletion)
|
|
* - 'dispense' (gets called by R::dispense)
|
|
*
|
|
* For every event type, this method will register this helper as a listener.
|
|
* The observable will notify the listener (this object) with the event ID and the
|
|
* affected bean. This helper will then process the event (onEvent) by invoking
|
|
* the event on the bean. If a bean offers a method with the same name as the
|
|
* event ID, this method will be invoked.
