Getting embeddable should trigger entity initalization

[mkosiedowski]

Getting public embeddables on lazy-loaded entity which is not initialized does not trigger entity initialization.

Common ProxyGenerator in \Doctrine\Common\Proxy\ProxyGenerator::getLazyLoadedPublicProperties uses code:

if (($class->hasField($name) || $class->hasAssociation($name)) && ! $class->isIdentifier($name)) {
    $properties[$name] = $defaultProperties[$name];
}

The interface \Doctrine\Common\Persistence\Mapping\ClassMetadata cannot be extended without breaking backward compatibility so ORM has to return true for embeddables either in hasField or in hasAssociation. In my opinion this should be hasField
