Export button - zip doesn't work for tables without single primary key

The export button for zip file (2pack) is not working for tables without a single-column primary key.

Failing test case:

• Log into GardenWorld with GardenWorld Admin role

• open Role window and navigate to role GardenWorld Admin

• Navigate to detail tab User Assignment

  • AD_User_Roles doesn't have a single-column primary key

• Push the export button, select zip type and uncheck Export current row only

• Verify the PackOut.xml file in the 2pack generated

Error:

It is exporting two times the same record for SuperUser, not the record we want to export.
