Detailed Description

Form element for handling rubric editor.

The rubric editor is defined as a separate form element. This allows us to render criteria, levels and buttons using the rubric's own renderer. Also, the required Javascript library is included, which processes, on the client, buttons needed for reordering, adding and deleting criteria.

If Javascript is disabled when one of those special buttons is pressed, the form element is not validated and, instead of submitting the form, we process button presses.
