The Remarks Module needs 3 new extension points to be added. They should be added to branches 1.6, 1.7 and trunk.
They are as follows:
org.openmrs.admin.encounters.encounterForm on encounterForm.jsp
org.openmrs.encounters.encounterList on encounterDisplay.jsp
org.openmrs.admin.observations.obsForm on obsForm.jsp
The remark portlet will use them to attache remarks.
I have attached a patch with the extension points.
The patch also contains the 'org.openmrs.patientDashboard.overviewBox' extension point because I didn't have it the firs time I downloaded 1.6 at the beginig of the project. I see it has been added in the mean time.
