[hibernate-issues] [Hibernate-JIRA] Created: (HHH-5097) Bug in ParameterizedFunctionExpression with two or more parameters: IllegalArgumentException
Bug in ParameterizedFunctionExpression with two or more parameters:
IllegalArgumentException
--------------------------------------------------------------------------------------------
Key: HHH-5097
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5097
Project: Hibernate Core
Issue Type: Bug
Components: entity-manager
Affects Versions: 3.5.0-Final
Environment: oracle 10g, hibernate 3.5
Reporter: Max Hartmann
If you call CriteriaBuilder.function() respectively
"ParameterizedFunctionExpression" with two or more arguments you get an
IllegalArgumentException.
I think the bug is here:
protected void renderArguments(StringBuilder buffer,
CriteriaQueryCompiler.RenderingContext renderingContext) {
for ( Expression argument : argumentExpressions ) {
buffer.append( ( (Renderable) argument ).render( renderingContext ) );
}
}
The arguments are not seperated by comma.
Exception:
Exception in thread "main" java.lang.IllegalArgumentException:

Code:
EntityManagerFactory factory =

EntityManager em = factory.createEntityManager();
CriteriaBuilder cb = em.getCriteriaBuilder();
CriteriaQuery<String> createQuery = cb.createQuery(String.class);
Root<TestBean> from = createQuery.from(TestBean.class);
Expression<String> param = cb.literal("DD.MM.YYYY");
createQuery.select(cb.function("TO_CHAR", String.class,
from.get(TestBean_.date1), param));
List<String> resultList = em.createQuery(createQuery).getResultList();
