loadDataObjects#

▸ loadDataObjects(item): Promise\<void>

Load the element's data objects into the instance data (appDelegate.loadDataObject), where they are saved with the instance: data.client for a data object 'client'. They load each time the element runs.

Parameters#

Name	Type
`item`	`Item`

failed#

▸ failed(item, error): Promise\<NODE_ACTION>

The task's work threw. With exceptionsAsErrors and an error event that catches it (by the exception's code, else its name; an error event with no code catches any), it is raised there as a BPMN error and the task ends. Otherwise the item's status is error, with the message, saved so the instance shows it and the item can be retried (engine.retry), and the exception is thrown to the caller as before.
