Lock Lost error on Work Item on clicking Advanced view



When using the OOTB Case Worker portal, you receive a lock lost error when you click on the "Advanced View" link in the Attachments section.

This behavior is not reproduced if the OOTB Case Manager portal is used (which has the same Attachments section).

Steps to Reproduce

1. Log in to the OOTB case worker portal.
2. Open a work item in your worklist or any workbasket.
3. Click on the "Advanced view" link on the "Attachments" section, a separate window opens up.
4. Submit the flow action of the opened work item to observe the error.
5. Execute the above steps in the Case Manager portal using the same attachments section and observe that there are no errors generated.

Root Cause
