Steps to Reproduce



1. Open the case type.
2. Click the ‘Configure process detail’ link for the stage.
3. Click flow name from the left side navigation to open the flow viewer.
4. Click the shape and select 'View Properties'. 


Root Cause



A defect in Pegasystems’ code or rules. A null check on the event object is missing in the _processActionModalOnlineHandler code.

Resolution



The shape properties can be viewed and modified using the navigation pane on the left or by opening the flow rule. The _processActionModalOnlineHandler code is updated in a future release to prevent the error.
