194: Type componentType = getNakedPropertyType(fromElement);
195: if (!componentType.isComponentType()) {
196: throw new QueryException("Property '" + getOriginalText() + "' is not a component. Use an alias to reference associations or collections.");
197: }

This occur if EJB3-QL query contains this errors:
update GroupDO set GroupDO._deleted = now() where GroupDO._id = ?1 and GroupDO._deleted is NULL

Correct query work fine:
update GroupDO set _deleted = now() where _id = ?1 and _deleted is NULL

This issue can also be reproduced with a select clause in the form of:

select c from customers c where c.lastname = :lastname

A rewritten query of the form

from customers c where c.lastname = :lastname

works fine.
