Unable to open a UI rule as a pop-up/tab



Unable to open a UI rule as a pop-up or tab.

Error Messages

Not Applicable

Steps to Reproduce

Open a UI rule (section/harness) from an activity or button click using WBOpen or WBOpenLaunch. The rule form opens but the design tab is displayed as blank.

Root Cause

The root cause of this problem is software use/operation error. The user has configured a link, on clicking this link a window is opened with a UI rule which is working fine in PRPC 6.3 SP1 but not working in Pega 7.1.7.


This is an expected behavior confirmed by the SME where we are not supporting the UI rules to be opened in the Pop-Up window. The user can use the OpenRule by parsing the InsHandle which will open in a new tab instead of the pop-up window.
