When you click on the history of the patient and select a prescription then the right patient is shown. So somehow the correct history seems to be selected. So really only the display of the patient after the scan is wrong.

It's not that the "wrong" patient is found, the functionality was implemented like that, preventing a change of patient if the prescription was in an edited state. Maybe the thinking was that if the doctor has started editing the medicines for a patient, it wouldn't make sense to change the patient and losing the changes for the previous patient. Up until now if the doctor wanted to reuse a prescription from a patient and use it for another patient, the change of patient needed to be the first step in editing a prescription. From now on, that is to resolve issue #86, it will be possible to replace the patient even for an "unsaved" prescription. Note that if the previous functionality is preferred it would make sense to disable the health card scanning if the prescription has been edited. This could be easily achieved.

So why does selecting a patient from the address book then work? It is only the scanning that does not work and not select the patient.

[bettar]

Selecting the patient from the address book works because in that case the "configuration" of the view controllers handled by SWRevealViewController doesn't change and the new patient data is just updated in the table view. When we use the scanning the view controllers are changed, and to go back to the Prescription view we end up calling viewDidAppear which loads different things depending on what is saved in the defaults and on the editing state.

Well lets see to it that selecting a patient by scanner works the same like selecting a patient manually.
