Hello, I have a UE script (BeforeSubmit) that triggers on 'XEDIT.' When a specific field is edited directly in the List, another field value is set. How can I get the list to update/show real-time vales in the List view? Currently, I have to refresh the list in order to see the update.

You can't get it real-time unfortunately (Netsuite doesn't do that stuff automatically). Best thing you could do is write your own Suitelet or Portlet and refresh it every so often (or perform an Ajax request to check if the data has changed and refresh it then).
