Applies to Pega Platform™ versions 8.7.1 and 8.7.2
After updating your Pega deployment to Pega Platform version 8.7.1, you notice that LiveUI automatically deletes Pega rules. In multiple applications, Pega rules are missing, and the system shows them as deleted.
You are using the LiveUI debugging tool in an application to open or check sections. You notice that the Pega-provided Section rules are deleted. For example, working in a DEV or QA environment as an application developer, you open a rule instance and notice that the rule is deleted automatically. When you look at the list of recently deleted rules, the deleted rule is displayed in that list. The deleted rule instance does not contain the Ruleset Name. You encounter this issue several times in one day.
This issue was reported for Pega deployments updated to Pega Platform version 8.7.1 for DEV and QA environments, both on-premises and cloud deployments.
Failure opening the Rule instance
This error displays when you are working with the Section rule form. Sometimes the error does not display on screen; instead, you see that rules are deleted and listed in the recently deleted rules list.
LiveUI contains a Pega defect that will be fixed in a future release of the Pega Platform and for Pega Cloud offerings.
pzLiveDesignViewDisplay, the step that calls the LiveUI method pxChooseBestRuleSet returns an error. This issue occurs when all your rulesets are locked. In pzLiveDesignViewDisplay, the call to pzChooseBestRuleSet fails because there are no rulesets to save your section. The error handling of this failure needs to work properly and not delete the open rule.
