Open Rule By Name action does not work in Pega 7

SA-10833

Summary



While clicking on a link which is configured to open a rule by name, user getts  "Failure opening the rule instance" error.

Error Messages



End user portal: Failure opening the rule instance

Tracer: Database.NotFound exception.


Steps to Reproduce



1. Create a link.
2. Configure the link with action - Open Rule By Name and provide insname of the rule to be opened.
3. Click on the link from the end user portal. Error can be seen on the screen.


Root Cause



The root cause of this problem is a defect in Pegasystems’ code/rules. 
The issue is occurring because the parameter insName is missing when the WBOpen activity is called.
The wrapper activity WBOpenLaunch activity which calls WBOpen activity passes a parameter “InsName” (with captial I) whereas WBOpen expects a parameter “insName”(with small i), hence the error.


Resolution



This issue is resolved through the following local-change: 

Use the Open Rule By Keys instead of Open Rule By Name on OnClick event to fix the issue.
