title: Refresh function in Oracle - APEX 5.1
body: <p>I'm using Oracle APEX to create a food ordering application. The application allows the user to add an item to their order through a popup window in which the user can select the quantity of the ordered item.
  My problem is that after the user adds the item to the order from the popup window the popup window is only closed and the main page is not refreshed. I have a PL/SQL region on the main page that prints the items chosen along with their prices and quantity so that region needs to be automatically refreshed after the popup is closed. How can I implement that?</p>
