Root Cause

A defect in Pegasystems' code or rules.

 The pxResults of D_pzGuardRailsToEvaluate data page is rendered classless. This leads to rule resolution issues and the sections load incorrectly.



Perform the following local-change:

Set Pega-Engine datapage/newgenpages Dynamic System Setting (DSS) to true.

This is resolved in the following:

  • Pega Platform 8.4.4
  • Pega Platform 8.5
