DiscriminatorMap recursion when using self-reference

New Feature Major Open Unresolved All Benjamin Eberlei Krzysztof Kolasiak Mon, 6 Aug 2012 18:54:11 +0000 Fri, 10 May 2013 15:29:53 +0000 2.3 ORM 1 4 <p>I have changed this into a feature request because you have hit the limitations of using inheritance and self referencing entities.</p> <p>Doctrine2 cannot currently lazy load UserBase#$sponsor because we don't know which proxy we have to insert. It can either be UserPerson or UserCompany. In order to know this Doctrine2 <em>has</em> to query the actual object to determine its type. The current strategy is then to load the actual entity because we have all data anyway.</p> <p>In order to implement this feature we need to insert a proxy instead of the actual entity. If we do that there should be no recursion happening.</p> <p>Reduced priority</p> <p>It'd be great if this is a configurable option.</p>
