[hibernate-issues] [Hibernate-JIRA] Issue Comment Edited: (HV-524) java.util.NoSuchElementException in type level validation using EclipseLink

java.util.NoSuchElementException in type level validation using EclipseLink --------------------------------------------------------------------------- Key: HV-524 URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-524 Project: Hibernate Validator Issue Type: Bug Components: validators Affects Versions: 4.2.0.Final Environment: EclipseLink 2.2.0 Reporter: sinuhepop Attachments: HV-524.zip When EclipseLink obtains an entity from database does a validation. It works ok with field level validators, but throws an exception with type level ones. The problem is that SingleThreadCachedTraversableResolver sends an "empty" pathToTraversableObject to EL's BeanValidationListener, who finally fails when calling "pathToTraversableObject.iterator().next().getName()". I don't know who (HV or EL) is responsible of the issue, but it worked with HV-4.0.2.GA. Thanks for your effort. Sinuhé.
