Description
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@test.com", 1); orderCase = orderCase.when("test2@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 at org.hibernate.ejb.criteria.expression.SimpleCaseExpression.render(SimpleCaseExpression.java:146) at org.hibernate.ejb.criteria.CriteriaQueryImpl.render(CriteriaQueryImpl.java:346) at org.hibernate.ejb.criteria.CriteriaQueryCompiler.compile(CriteriaQueryCompiler.java:223) at org.hibernate.ejb.AbstractEntityManagerImpl.createQuery(AbstractEntityManagerImpl.java:441)
