I am trying to make this Date Popup Authored work together with http://drupal.org/project/override_node_options which lets the site administrator give users without "administer nodes" possibility to change specific options of the node, such as "authored on". However, when I enable "override [content type] authored on" for a specific user role they don't get the date picker, just the normal date field. Only users with "administer nodes" get the date picker.
Could this be because of module weights?
Feel free to move issue to override_node_options if you think it belongs there.
