Custom calculated database field/column breaks List View context menus and icon actions with a concurrent modification exception - Known Error

Custom calculated database field/column breaks List View context menus and icon actions with a concurrent modification exception Description After Rome upgrade, a form with a custom database field/column is non-functional in List View. Context menus and icon actions do not work.

Steps to Reproduce

Create a new custom column on the Knowledge [kb_knowledge] table in a Rome instance:

Type: Integer

Column name: u_compiledroles

Application: Global

Attributes: edge_encryption_enabled=true

Calculated value: current.roles.toString().length;

Workaround This problem has been fixed. If you are able to upgrade, review the Fixed In section to determine the latest version with a permanent fix your instance can be upgraded to.

The workaround is to temporarily remove the calculation from the field, then add the field to the list, then restore the calculation. If the field is in the list, the list loads as expected.
