I must admit you have a good point here. The reason for
wanting to pull up 'anyone' or the last patient is merely
technical because it makes coding quite a bit safer (eg. you
can assume to *always* have a valid patient object availble -
now, Horst is likely to attest that one can never be sure of
that ;-)   Anyways, I agree that we should not confuse the
user.

I have tried to make it irrelevant whether there is a real
patient object active by assigning a Null pattern instance to
the patient pointer in the nonselected-patient case. However,
that seems to not work.

Technically, the next best solution is to force the user to
define a plugin that is raised initially and which doesn't
need an active patient. Thereafter switching to tabs needing a
patient isn't possible before actually selecting a patient.
This solution also feels fairly OK in terms of user logic.
What do you think ?
