3738663 - RAP validation message not displayed in UI for child/grandchild entity when %PATH is missing

• A RAP validation adds an error to REPORTED for a child/grandchild entity, but the message does not appear in the UI.
• Records can be saved even when a field is initial because the validation does not block save.
• After adding FAILED, an exception occurs but the UI still does not show the message.
