> When running UG2 under heavy we sometimes see the exception below when a new Entity is created by an HTTP POST.
> The problem seems to be that we write the Entity. Then when we add-to-collection and validate the Entity, we read the Entity but it is not ready for us to read yet -- so the read fails.
> Instead of re-reading the Entity, we should pass the Entity that we created down into the add-to-collection and validate methods. We should not need to read the Entity in the processing of the request that created it.
> java.lang.NullPointerException
