[weld-issues] [JBoss JIRA] Commented: (WELDX-177) add getSingleResult() to PropertyQuery

add getSingleResult() to PropertyQuery -------------------------------------- Key: WELDX-177 URL: https://jira.jboss.org/browse/WELDX-177 Project: Weld Extensions Issue Type: Feature Request Affects Versions: 1.0.0.Beta1 Reporter: Dan Allen Fix For: 1.0.0.Beta2 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.
