SA-27438

Summary

Referencing a single-page property in a Rule-Utility-Function parameter of Clipboard page type generated Java, which created a clipboard property at run time, resulting in a classcast exception. When the primary page is a single page, like pyWorkPage method, it works fine. When the primary page is like pyWorkPage.ABC, system throws Classcast exception on runtime and does not pick the activity.

Error Messages

** Java Exception: java.lang.ClassCastException: com.pega.pegarules.data.internal.clipboard.ClipboardPropertyImpl incompatible with
com.pega.pegarules.pub.clipboard.ClipboardPage

Steps to Reproduce

Use @Utilities.pxExecuteAnActivity (Primary,"ActivityName") function as an expression in a rule.

Root Cause

All type conversions for the broken expression are skipped because VFORM_PEGA_PAGE_REFERENCE (in one of the Java classes) returns false from isValueLikeOrParam().

Resolution
