I have created a rather large form using drupal7 webform. All was going well. I would clone an item, drag it to a new place and the weight would change to reflect the move. However when I reached 1000 components, each new one added or cloned would not move. If it did, it did not stay moved after a save. All the new additions in excess of 1000 have the same weight, and I can't change it. Even tried renumbering in the negative to no avail. What to do?
