Error while adding/deleting OR condition row in a decision table



User is getting error while adding /deleting OR condition row in a decision table.

Error Messages

"insertOR: TypeError: Cannot read property 'findFirstParentNamed' of null"

Steps to Reproduce

Configure a decision table.

Root Cause

A software use or operation error : User compilation.


User has observed that ruleformutilitymanager.js file is not loading as expected at user end, hence required javascript objects are not initialized as expected which is resulting in the error while adding the OR row in decision table.

After following the below steps to clear the cache, then it is working as expected.

1. Stop application server and remove the contents(folders and files) of Pega temp directory in application server.
2. Do a re-start of the application server by removing the PegaRULES_Extract_Marker file.
