Details

This event is defined in the undo extension, so you need to enable the undo plugin. Read the details in the Undo/Redo Functionality article.

The action parameter presents an array of command objects, each of which includes the following set of attributes:

type - (string) the type of a command: "add/remove/update"
entity - (string) the type of the object which was changed: "task" or "link"
value - (object) the changed task/link object
oldValue - (object) the task/link object before changes

If no changes were applied, the action argument will be === null. It can happen when gantt.undo() was called, but changes were canceled by onBeforeUndo or the stack was empty.
