Relationships should not be displayed on the short patient form when the "new_patient_form.showRelationships" global property is not set or is set to a value of false.
To reproduce this, set the global property named "newPatientForm.relationships" to a value like: 1a,1b,2a,2b,3a,3b,4a,4b
Then set the global property named "new_patient_form.showRelationships" to a value of false, or simply leave it empty.
Search for a patient. Ensure that he or she has some relationships by adding a few as necessary using the "Overview" tab of the patient dashboard.
Go to the "Demographics" tab and click the "Edit this Patient (Short Form)" link.
You will be taken to the short patient form and see that relationships are displayed yet they are not supposed to be because of the value for the "new_patient_form.showRelationships" global property.
So i think the fix should be to add a check for the global property's value in the "shortPatientForm.jsp"
