When capturing Medical Certificate of Cause of death on our COD instance, It was observed that the date of death was allowing future date to be captured. the date being for date of death is the system date for event capture.
This was tested on trainingland using antenatal visits event program and same problem was observed for all stable versions of DHIS2.
There is the need to fix this and probably replicate the checkbox that allow users to either decide to capture future dates or not as implemented in tracker programs under the enrolment details. Default should current and previous date while a check box can then be added to allows users to check if they wanted allows capture of future dates in their event programs.
