- Sometimes an application cannot change the patient. If the user tries to change the
patient in one application, it notifies the context manager, which surveys the other
applications. If some app cannot accept a page the user receives a dialog identifying the
stuck application and may switch to the other application and fix it, or ask the current
application to leave the context. They might choose the the latter course when
they are doing a quick patient lookup in response to a phone call and intend to return to
the prior patient quickly.
- The specifications includes certain icons and other user interface elements that
applications adopt to indicate that they are out of the context in a uniform way.
- This trace diagram shows a successful switch.
