The surname is used just as an example of a field.
The NullPointerException is because the same field "id" tries to use
it's own value in a template. The template cannot contain the same
field on which it is being applied. I'd suggest that you get the id
aliased to another name, for example using a query "select id as
idAlias from vets" and then use:
<field column="id" template="vets-${vets.idAlias}" />
That should work, let me know if you face a problem.
