[#3698] - schedule with start and/or end date cannot be saved

Hi all,

When the Jasperserver locale is set to "de" I get the error "Ungültiges Datum" (="invalid date") whenever i try to save a schedule with a specified start date and/or end date.

Environment:
JasperServer Version 5.6 (bundled JRS installation without any configuration changes)
Tomcat 7 (from bundled JRS installation)
Postgre database (from bundled JRS installation)
Java 7
IE 11

Error reproduction:
- Choose locale "de", "fr" or "es" on login page and log in.
- Open schedule list of a report.
- Choose "Create schedule".
- Choose start date by means of the datepicker control.
- Hit "Save".

Normal/expected behaviour:
A small popup will appear, that asks for a name and description of the schedule, and on hitting "save" the schedule dialog will close, the schedule list will be displayed and the newly created schedule appears in this list.

Experienced/faulty behaviour:
No popup. Instead a small red error message is displayed under the offending date field which states that the date is not valid ("Ungültiges Datum", "Date non valide", "Fecha no valida").

I tried this with localization set to german, french and spanish, all with the same error.
However with localization set to english, the error does not occur.

Actually we experienced this issue in version 5.5 too, but we could circumvent it by fixing the UI_DATE_PATTERN in scripts/scheduler/model/job.js to german and passing it as a parameter in calls to method "moment"
(as described here: http://community.jaspersoft.com/jasperreports-server/issues/3637)
Unfortunately this does not work anymore with version 5.6.

Any help appreciated!

Regards,
Jasmine
