Failure opening the Rule Instance.
When traced @baseclass.WBOpen fails at step 3 with the fail message
Steps to Reproduce
Try to open the operator record, access group record, or any rule from the Application Explorer.
The root cause of this problem is a defect/misconfiguration in the operating environment combined with an error in Pegasystems code.
When running Internet Explorer 8, the operation tries to open the rule in a new window, and there is a fixed bug in Pega 7.1.8 which involves a missing parameter to perform WBOpen when trying to show the rule in a new window.
This issue is resolved by making the following change to the operating environment:
Upgrade to a new version of Internet Explorer, and the rule will open in a tab instead of a new window.
This exercises different code, avoids the bug, and has a successful conclusion.
