Date format ignored in 6.2.0

My input control waiting for :

Date Format: yyyy-MM-dd

Timestamp Format: yyyy-MM-dd'T'HH:mm:ss

So I modified the file jasperserver_config_fr.properties to customize my date , but no effect.

# Used for parsing and formatting dates by server

date.format=dd-MM-yyyy

datetime.format=dd-MM-yyyy HH:mm:ss

time.format=HH:mm:ss

# Used for parsing and formatting dates by calendar component (UI).

# Pattern for date should match appropriated pattern from server properties.

calendar.date.format=dd-mm-yy

calendar.datetime.format=dd-mm-yy HH:mm:ss

calendar.time.format=HH:mm:ss

I also changed the file jasperserver_config.properties , and no effect.

# Used for parsing and formatting dates by server

date.format=dd-MM-yyyy

datetime.format=dd-MM-yyyy HH:mm:ss

time.format=HH:mm:ss

calendar.date.format=dd-mm-yy

calendar.datetime.format=dd-mm-yy HH:mm:ss

calendar.time.format=HH:mm:ss

Whereas with the version 5.5.0 when I changed this files everything worked.

v 6.2.0
