Date Picker pop up does not display in modal dialog window



After opening and closing an overlay in the modal dialog, the Date Picker pop up does not display.

Error Messages

Not Applicable

Steps to Reproduce

  1. Create a Date Picker control and an overlay.
  2. Open the Date Picker and overlay in a modal dialog.
  3. Close the overlay. Open the Date Picker after closing the overlay.

Root Cause

A defect in Pegasystems’ code or rules.

The center overlay condition is unchecked and is still true while closing the overlay. Hence, when the Date Picker is opened the second time, the CSS for the calendar is not calculated. Therefore, the calendar opens beyond the screen.


Apply HFix-43025.
