Jira issue originally created by user sebastian.hoitz:

I have a model which looks like this:

Class A
protected $collectionB = array(); // Holds many Class B instances
protected $collectionC = array(); // Holds many Class C instances

Class B
protected $classC; // Holds one Class C instance

Class C
protected $attributes; // Holds many attributes which are stored in another entitty with SINGLE_TABLE discriminator

When I try to persist my object to the database, Doctrine causes this error:

Message: spl*object*hash() expects parameter 1 to be object, array given

I assume that this might happen, because of the Class B holding one Class C, and Class A also holding some Class C instances.

Those are, in some cases, the same. So when a new Class B is added, together with a new Class C, this new Class C is also added to Class A.
And somehow internally the already persisted Class C (Class B is getting persisted first) transforms the Class C instance into an array, and Doctrine can't save it anymore.

This is my guess of what happens. When I skip adding all the Class C instances to Class A, I don't get this error.
