Jira issue originally created by user omega:

I have an entity which has a many to one relationship pointing to itself. This is ultimately set to map parent/child relationships.

Consider the following snippet:

    // Start out assuming we are searching for "Pages" with no parent specified (root level).
    $parentId = null;

    // Check to see if we're fetching pages that are a child of a parent.
    if(array*key_exists("parent_id", $*GET)) {
        $parentId = $*GET['parent*id'];
    }

    $pages = $this->entityManager->getRepository("MyNamespace\Models\Page")->findByParent($parentId);

When this code is run, PHP tells me:

PHP Fatal error:  Uncaught exception 'Doctrine\\ORM\\ORMException' with message 'You need to pass a parameter to 'findByParent''

At which point, it's obvious that it's expecting a parameter an receiving none. The problem here however is that I have no way of matching for null. Is there some kind of surrogate null php-class that can be created to represent a model-null?
