You may encounter a weird problem when "Apply" button to run a report in Jasper server doesn't do anything and there's no error in the Jasper log.
In my case the reason for that was missing user attribute which was referenced in the report, e.g. for report parameter LoggedInUserAttribute_regionId, the corresponding user attribute regionId was not set.
