Jira issue originally created by user gedrox:
Problem is that UnitOfWork::doMerge() calls ClassMetadata::getIdentifierValues() for the entity but that function doesn't have case for not initialized proxy. It just reads the Id properties from the object's reflection.
It should load the proxy or get the ID stored inside the proxy object or doMerge must initialize it maybe.
Comment created by gedrox:
I have taken the DDC353 test as the base for this test case.
Hopefully it works because I have executed it in slightly different version without the Doctrine tests environment.
Comment created by @beberlei:
Issue was closed with resolution "Fixed"
I would put the changes inside the method getIdentifierValues not before it's execution.
Isn't it plausible that it is called with not initialized proxy from somewhere else?
