Design Tab not rendering for harness rules
The design tab is not rendering correctly for harness rules (the tab is shown, but is completely empty)
Steps to Reproduce
Open a Harness
The root cause of this problem is software use/operation error which caused an instance of RULE-FILE-TEXT WEBWB PZHARNESSRULEFORMUTILS to be mistakenly deleted. A user most likely omitted the trailing underscore in:
DELETE FROM PR4_RULE_FILE WHERE pzInsKey LIKE 'RULE-FILE-TEXT WEBWB PZHARNESS_%'
when attempting to use the above command to clear cache tables.
This issue is resolved through re-importing the rule from an available Pega-UIDesign ruleset.
