Project: Hibernate Core
Issue Type: Bug
Components: query-criteria

Environment: SQL Server 2005
Reporter: Anne Buit
Priority: Minor
Attachments: SimpleCase.zip
When creating a SimpleCase using CriteriaBuilder.selectCase(Expression<?> arg0), a
classcast exception will be thrown when the query is rendered to a TypedQuery.
CriteriaQuery<Customer> query = builder.createQuery(Customer.class);
Root<Customer> root = query.from(Customer.class);
query.select(root);
SimpleCase<String, Integer> orderCase =
builder.selectCase(root.get(Customer_.EMail));
orderCase = orderCase.when("test(a)test.com", 1);
orderCase = orderCase.when("test2(a)test.com", 2);
query.orderBy(builder.asc(orderCase.otherwise(0)));
em.createQuery(query);
Exception in thread "main" java.lang.ClassCastException: java.lang.String cannot
be cast to org.hibernate.ejb.criteria.Renderable
