Error Messages

Steps to Reproduce

1. Open Sample Decision Table.
2. Click edit in excel button.

Root Cause

SSO (httponly cookie) is enabled in QA and Production instances. On debugging the JS file - pega_desktop_decision.js, it is found that the strConnID is passed as null inside the edit_in_excel function which results in the issue. 

var strConnID = zUtil_GetCookie("Pega-RULES"); 
if(strConnID == null) strConnID = ""; 


Add the null check after the strConnID definition under HFix-23555 in Pega 7.1.6.
