In receiving screen, replace "this list has no items" with dots

Purpose: When beginning the receiving process, or changing to receiving history, the screen shows "This list has no items" until the POLs or pieces are displayed. That's a confusing message.

As a staff person
I want a "working/loading" indicator (like three dots) until the POLs or receiving pieces display on the receiving screen, instead of "This list has no items"
So that I know to wait for information to fill in, instead of being told there's no information

Scenarios

1. Scenario 1
   • Given an Open PO
   • When the user clicks on Receive to open the receiving screen
   • Then show three dots that cycle, to show that data is being filled in, until the POLs are displayed
2. Scenario 2
   • Given the Receiving screen/Receiving items pane
   • When the user clicks on the Receiving History tab to display the receiving history
   • Then show three dots that cycle, to show that data is being filled in, until the receiving history is displayed
3. Scenario 3
   • Given the Receiving screen/Receiving history screen
   • When the user clicks on the Receiving items tab to display the receiving items pane
   • Then show three dots that cycle, to show that data is being filled in, until the receiving history is displayed
4. Scenario 4
   • Include standard automated testing coverage; add screenshot or other details to confirm test coverage is in place

NOTE Other areas of FOLIO use the three dots to indicate that the system is processing, so you should be able to find that component and reuse it
