[ https://issues.apache.org/jira/browse/OPENJPA-1802?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Kai Feng Zhang updated OPENJPA-1802:
------------------------------------
Summary: Query throws exception: java.lang.ClassCastException: org.apache.openjpa.util.Id (was: Named query throws exception but normal query works)
> Query throws exception: java.lang.ClassCastException: org.apache.openjpa.util.Id
> --------------------------------------------------------------------------------
>
> Key: OPENJPA-1802
> URL: https://issues.apache.org/jira/browse/OPENJPA-1802
> Project: OpenJPA
> Issue Type: Bug
> Components: query
> Affects Versions: 2.0.1
> Reporter: Kai Feng Zhang
> Attachments: EmailDb.java, ListFieldDb.java, PersonDb.java
>
>
> I have a named query on PersonDb entity,
> @NamedQuery(name = PersonDb.FINDBY_PERSONID, query = "select p from PersonDb p where p.id = :id "),
> Then I use following code to get person entity:
> Query q = entiyManager.createNamedQuery(PersonDb.FINDBY_PERSONID);
> // Query q = entiyManager.createQuery("select p from PersonDb p where p.id = :id");
> q.setParameter("id", uid);
> q.setFirstResult(0);
> q.setMaxResults(1);
> List<?> plist = q.getResultList();
> Person person = null;
> if (plist != null && !plist.isEmpty()) {
> person = (Person) plist.get(0);
> }
> There is exception then. But if I use createQuery() as the commented line, it works, and person is got from table.
> The exception from name query is:
