public class AssociateWithPage : InvokesBase<AssociateWithPage>

If a workflow instance is associated with a page, only page events concerning that page will be delivered to the instance. For example, if a workflow instance is interested in a specific page version being published, if that instance is associated with the page, only publish events for that page will be delivered. If a workflow instance is started from a page related event, the instance and the page will be automatically associated. If a workflow instance is interested in an event regardless of which page caused the event (e.g. the instance is interested in when a page is deleted) then the instance can call AssociateWithPage with the PageLink value set to EmptyReference.
