Jira issue originally created by user gediminasm:
Currently $class->isIdentifierComposite value stays "false" if no new identifiers were added on child class..
around line 270, file: ClassMetadataFactory.php
$class->isIdentifierComposite = $parent->isIdentifierComposite;
this way if supperclass had composite identifier and child had none identifiers
the result would be as suspected.
