Product Description

Bug fix: Fixes form navigation error due to multiple search callout extras

Repro:

1. Use case search list callout to search and filter the case list
2. Make a case selection to enter into a form
3. Exit the form without saving and go back to the case list
4. Select the case again from filtered case list and go into the form again
5. Form errors with an error -"Multiple Extras found with key entity-list-data"

Technical Summary

On making a case selection from the case list filtered with a callout, we add an extra called entity-list-data to the top frame step. On re-selecting the case from case list, this extra ends up getting added again to the frame step which eventually errors when user opens the form with exception thrown from here.

Safety Assurance

• If the PR is high risk, "High Risk" label is set
• I have confidence that this PR will not introduce a regression for the reasons below
• Do we need to enhance manual QA test coverage ? If yes, "QA Note" label is set correctly

Automated test coverage

None.

Safety story

Small change to remove the extra before adding. Locally tested.
