When rule form opens blank



The tab is displayed on opening any When rule in the system, but the main frame is entirely blank. This does not occur with other rule types.

Error Messages

Not Applicable

Steps to Reproduce

1. Login as a developer.
2. Open any When rule.

Root Cause

The root cause of this problem is a defect or misconfiguration in the PRPC operating environment. When rule form content was corrupted in the static content cache on the PRPC server. As a result, a blank HTML file for the rule form was sent. This caused the blank rule on open.


Perform the following change to the PRPC operating environment: 

1. Shutdown the PRPC server(s).
2. Delete contents of the PRPC temporary directory completely.
3. Delete the temporary internet files cache in the browser completely.
4. Restart the PRPC server.
