Validation referencing page list cannot resolve Page List class
Attempting to configure a validation rule on a pxResults() page fails as the smart prompt does not populate with the list of available validation rules
On entering the validation rule name manually and clicking the open icon a new rule dialog is presented with the following error:
"Class key validation failed for class: Rule-Obj-Class, class key value: $CLASS, reason: Instance not found"
HFix-20128 corrects this behavior.
Note, that the validation rule will need to be recreated after installation.
