Description

To reproduce:

• for simpleapp, introduce a child entity (not cascade)
• delete parent entity to force an FK exception (due to child entities still present)

this results in a 500 html exception (RestartResponseException).  the FK exception messages are queued and only rendered subsequently.

(Also, see two exceptions queued, one warning - orange - and one error - red).
