Idea Summary
Include a "Show Wait Popup" property in "Execute Server-side Code" actions

Use Case
When we have to execute a PL/SQL code in a Dynamic Action that can take a few seconds to complete, we always use javascript before the action to create a Spinner, and another Javascript after to remove it.

This could be done with just a single property in the "Execute Server-side code" action

Preferred Solution (Optional)
Include a "Show Wait Popup" property in "Execute Server-side Code" actions, True/False
