Repeat grid does not display property values

Steps to Reproduce

  2. Create a repeat grid using the page list property

  4. Traverse back in the case and review the details of the repeat grid

Root Cause

A backwards compatibility defect in Pegasystems’ code or rules. The data page, which populated the grid's source property, had classless pages in pxResults and displayed InvalidParameterException while invoking getClassName(..).
