> When EclipseLink obtains an entity from database, it 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 
> {code}
> pathToTraversableObject.iterator().next().getName()
> {code}
> 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.
