Overview: Optimistic locking message for an instance in a non-consortial tenant is not displaying properly. This may relate to the work being done on MODINV-860.

Steps to Reproduce:

1. Log into Snapshot as a user with Inventory permission to edit instances

2. Go to Inventory

3. Find an existing instance

4. Open the instance details

5. Open a second window and copy/paste the first screen's URL into the second window

6. In both windows, click Action/edit instance to get to the Instance editing screen

7. In the first window, assign or change the instance status. DO NOT press save yet

8. In the second window, add a statistical code to the instance

9. Press save in the second window and confirm that the instance was updated, with the statistical code added to it

10. Go back to the first window and press save

Expected Results: User receives a message that this is not the most recent version of the instance, and an option to view the latest version or cancel.

Actual Results: User receives a pop-up message, but it does not have the proper information in it.

Additional Information:

• This works properly for holdings and items. Only instances are having a problem

• This works properly in Orchid, so something has regressed in Poppy

• Video and correct alert message versus incorrect alert message attached

Testing details

• Review the optimistic locking tests already in TestRails - determine if we need to add any for the various scenarios listed below

Note that optimistic locking must work as follows:

• Non-consortial tenant

  • For instances, holdings, and/or items being edited at the same time by

    • The same user with 2 windows open

    • Two or more users

• Consortia central tenant

  • For shared instances being edited at the same time by

    • A user in central tenant and the same user in a member tenant

    • The same user in 2 different member tenants

    • One user in central tenant and a different user in a member tenant

    • Two different users in two different member tenants

• Consortia member tenant

  • For shared instances being edited at the same time by

    • A user in central tenant and the same user in a member tenant

    • The same user in 2 different member tenants

    • One user in central tenant and a different user in a member tenant

    • Two different users in two different member tenants

  • For one member tenant's holdings being edited at the same time by

  • The same user with 2 windows open

  • Two or more users in the same member tenant

  • For one member tenant's item being edited at the same time by

  • The same user with 2 windows open

  • Two or more users in the same member tenant
