com.pega.pegarules.pub.generator.RuleNotFoundException: Failed to find a 'RULE-OBJ-WHEN' with the name 'MYWHENRULE' that applies to '@baseclass'. There were 2 rules with this name in the rulebase, but none matched this request. The 2 rules named 'MYWHENRULE' defined in the rulebase are:
2 related to applies-to class '@baseclass', but were defined on subclasses: 'Myco-FW-EForm-Work'

Steps to Reproduce



Click on the harness screen menu items.

Root Cause



An application activity was renaming the pyDisplayHarness page to something else, after which the out-of-box Rule-Navigation.pxProcess activity attempted to use the nonexistent page.
