Finance optimistic locking

Purpose:

UI for optimistic locking.

User story statement(s):

As a user,
I want to have a clear message when a 409 error occurs when saving the record
so that I can load the latest version.

Requirements:

• Apply to the following edit record screens: fiscal year, ledger, group, fund, budget. Is it possible to do something similar for fund type and expense class in settings ?
• If user hits Save and a conflict is detected then display Conflict detection banner.
• Clicking View latest version link displays AS IF the user hit Save & close and it was successful AND display update record in a new window/tab
  • If possible have focus go to pane header
• If user hits Cancel or X on the Edit form then show Are you sure modal?
• When user hits Save & close, make sure focus returns or remains on the conflict detection banner.

Scenarios:

Given the user A is editing a record
AND user B has just edited and saved the same record
Thus user A is not editing the latest version
When user A hits Save on that record
Then display the conflict detection banner right below the paneheader

Given the user A is editing a record
AND user B has just edited and saved the same record
Thus user A is not editing the latest version
When user A hits Cancel or x on that record
Then display the standard "Are you sure?" modal used to alert the user to unsaved changes before they navigate away from the edit screen
(And if User A keeps editing and then presses Save, then display the conflict detection banner)

Given conflict detection banner displays on a record
When user A clicks on View latest version
Then display in a new tab in View mode (not Edit mode), with the most recent edits that have been saved

Given conflict detection banner displays on record
When user A hits Cancel or X
Then discard User A's edits and return to a View version of the record

Given conflict detection banner displays on the record
When user A hits Save again
Then shift focus to the conflict detection modal
