Dynamic Actions with Multiple Triggering Elements
Dynamic actions also give you the opportunity to define multiple triggering elements.
Using this method, you only need to create a single dynamic action to catch the events
of several page items.
Your public ticket-entry page contains several page items that shouldn't be left
blank. However, your APEX validations won't fire until the user submits the page. In
this exercise, you create a dynamic action that checks each of these page items as you
navigate through the form to see if you left the value null. If the value is null, the back-
ground color of the item will be set to pink using the background style element. If it is
not null, the background of the item will be set back to white. Follow these steps:
