Steps to Reproduce

  1. Open the application definition.
  2. Click Edit or Review warnings.
  3. Enter text.
  4. Click Cancel.
  5. Click Edit or Review warnings.
  6. Enter text.

ROOT  CAUSE

A defect in Pegasystems’ code or rules.
The pyModalPageCancelAction activity was overridden in PegaFS:08-01-01. At Step 2, the pyLanding.pyLandingNavigation.pyLevelC=="SampleDataManagement" When condition corrupted the pyLanding page and the user was unable to justify the guardrail warnings.
