we have a made a custom review form with some requested fields. If a reviewer tries to submit a review with one of those fields empty, the form remains open but no error message is shown. The notification of a missing field is at the side of the empty form item but the reviewer has to scroll the form to find it. We have had cases when a reviewer has left the page wondering if the review is submitted. You should add an error message to the cases when there is an error, not just stall the form. In our case, when the reviewer tries to submit a form with an empty field, a message “A requested field is empty” should be shown so that the reviewer knows to look through the form. We use OJS 3.1.0-1.
