DialogCreationFeature

public interface DialogCreationService

extends Service

This is a Service that creates new dialogs.

It may be provided by a Session to create new independent dialogs. I.e. in its lifecycle the new dialog depends only on the lifecycle of the session.

Equally a dialog (e.g. a portal) may provide this service to offer other dialogs to create new sub dialogs. The life cycle of the sub dialog depends on the lifecycle of the dialog that provides this service.
