Timeline control architecture
The Timeline control displays the timeline view of a case.
The D_WorkHistory data page passes with the parameter pzInsKey as a source for the Timeline control. Only custom audits display, because the data page retrieves the custom audit and filters the default audit.
EventSection (History-Work-) displays the messages in the audit. This section has a simple list layout that contains the pyMessageKey (audit message) and pyPerformer (operator name) properties.
The pxTimeCreated property is a reference for the event start date property.
