Issue

Upgrading to K2 4.7 results in being prompted to regenerate the K2 SmartObjects for all the lists and libraries. 

- All list and libraries were successfully regenerated.

- SmartObjects "Get Document By ID" and "Get Document Metadata by ID" run successfully.

- When trying to run "Get Documents" or "Get Documents Metadata" on any of the libraries, the error below appears:

"ErrorGeneral","0","ErrorMessage","SharePoint Broker","0 System.MissingFieldException: Field not found:

Symptoms

This issue occurs when you create a new document library and a new custom list, both without any custom fields, and then create a SmartObject for these libraries.

Executing the method "Get Documents" or "Get Documents Metadata" on any of the libraries via the SmartObject tester tool will produce the error.

Resolution

To resolve this issue, run a K2 Blackpearl repair via the installation media.

We recommend running a K2 SmartForms repair as well.

Once the repairs are done, reinstall any Cumalative Updates and Fix packs that were applied.
