This appears to be due to believing that the Bulletin will be set in the
BulletinEntity, but DtoFactory creates a bulletin thus:
{code}
public BulletinEntity createBulletinEntity(final BulletinDTO dto, final boolean
canRead) {
final BulletinEntity entity = new BulletinEntity();
if (dto != null) {
entity.setId(dto.getId());
entity.setSourceId(dto.getSourceId());
entity.setGroupId(dto.getGroupId());
entity.setTimestamp(dto.getTimestamp());
entity.setNodeAddress(dto.getNodeAddress());
entity.setCanRead(canRead);
if (canRead) {
entity.setBulletin(dto);
}
}
return entity;
}
{code}
So the bulletin may not be populated
