-----------------------------
Assignee: Dan Allen
> add getSingleResult() to PropertyQuery
> --------------------------------------
>
> Key: SOLDER-41
> URL: https://issues.jboss.org/browse/SOLDER-41
> Project: Seam Solder
> Issue Type: Feature Request
> Reporter: Dan Allen
> Assignee: Dan Allen
> Fix For: 3.0.0.Beta1
>
>
> PropertyQuery should offer the method getSingleResult() for the same reason
> it exists in the JPA Query interface: to fetch a single result but also
> assert that there is only one result to be fetched. If more than one property
> is matched when getSingleResult() is called, an exception will result.
> Using getFirstResult() to return exactly one result is inappropriate (and
> could lead to bugs) because it could hide the fact that multiple properties
> are being inadvertently matched. As a workaround, the developer would
> currently have to run getResultList() to ensure only one property matches.
> Offering a getSingleResult() would resolve these issues.
