Refresh Error

The refresh error is a bit annoying, especially if one is using draggableviews in a non admin way.. As a temporary solution, I simply tossed in a node presave function into a module.. thought I would post it so that others could do the same until a solution is found which removes the need for such function. Note, this will not always work unless you never enter a value into the integer field.. a simple way to ensure that this always happens is to unset the field using a form_alter.

/*
 * This is a quick fix to the problem with draggable views which causes an error
 * if more than one node has the same value for integer. Therefore, unless the
 * user has set the integer field, then it is set to the node created unix timestamp.

function modulename_nodeapi(&$node, $op) {
  switch($op){
    case "presave":
        if(!isset($node->field_integer[0]['value'])) {
          $node->field_integer[0]['value'] = $node->changed;
        }
      break;
  }
