Blank screen when quickly switching tabs after validation error



When submitting a screen flow [action], and then quickly changing tabs, this causes a blank tab when you get back to the tab where you finished the assignment. This is only reproducible on IE11. 

HFix-21574 addresses that scenario but if you also introduce a validation error when you submit the flow action, the same sort of blank screen issue is seen again.

Error Messages

Not Applicable

Steps to Reproduce

  1. Open at least two tabs.
  2. Submit screenflow (and introduce a validation error)
  3. Quickly click a different tab

Root Cause

A defect in Pegasystems’ code or rules.


Apply HFix-27152 which addresses both scenarios with and without validation errors.
