New CaseID mapped to my Text1 property Audit note added here with expression including property reference
Custom version of pyCaseHistoryContent for this case type Custom version of pyCaseHistoryContent for this case type. Changed the Description column of the grid to reference a custom section.
Section has 2 layouts with visible when condition to determine when to show the link version. Layout 1 is a copy of the original History gird Description configuration using the DisplayAsLiteralLocalize control. Layout 2 is link referencing pyWorkPage.Text1 where CaseID is stored (Need to define pyWorkPage on Pages & Classes).
Now when I run my case the audit for the new case is a link that will open it.
