Does FM support varargs or arrays in method calls?

Hi,

This is interesting, I might be in trouble here - hopefully I'm just missing something.   Consider this,

class WrappedObject  {
      public <E extends Entity> java.util.List<E> findByNamedQuery(Class<E> entityClass,
                  String query, Object... queryParams) {
            return entityManager.findByNamedQuery(entityClass, query, queryParams);
      }
}


class EntityManager  {
      public <E extends Entity> java.util.List<E> findByNamedQuery(Class<E> entityClass,
                  String query, Object... queryParams) {
            // do hibernate stuff here
      }
}


[#assign results = wrappedObject.findByNamedQuery(${class}, "findByFirstAndLastName", ["John", "Smith"]) /]

Should work right?

: freemarker.template.TemplateModelException: No signature of method findByNamedQuery matches (java.lang.Class,java.lang.String,freemarker.ext.beans.SequenceAdapter)

If I forget about the varargs and change the wrapped objects method to use Object[] queryParams, I get the exact same exception.  However if I change it to List<Object>, ["John", "Smith"] matches the rule, and the method gets invoked.

That's ok, but I can't change the API of the EntityManager class - we're stuck with varargs there.  So,


class WrappedObject  {
      public <E extends Entity> java.util.List<E> findByNamedQuery(Class<E> entityClass,
                  String query, List<Object> queryParams) {
            return entityManager.findByNamedQuery(entityClass, query, queryParams == null ? queryParams : queryParams.toArray(new Object[queryParams.size()]));
      }
}

I really thought that would work.  Unfortunately, all it does is pass in 1 parameter to entityManager's method, an Object[] - not Object, Object.  Interesting.  Any ideas?  Is there different syntax for arrays & lists?

Any help is greatly appreciated.

Thanks,
john
