[FLOW3-general] inheritance and repositories

[Mathis Hoffmann]

Hi!

I've got one more question concerning inheritance in FLOW. Setup is as 
it was before: One abstract Customer class that has two concrete child 
classes, BusinessCustomer and PrivateCustomer. The Customer class has a 
@ORM\InheritanceType("JOINED") annotation and I do have a 
CustomerRepository that enables me to access, update and delete objects 
of both type, Business- and PrivateCustomer[s]. So far everything works 
well. I have created a CustomerController that is able to list all 
customers. Now I want to implement an update-method in this controller. 
I tried to write it using the following signature:

public function updateAction(HdM\Accounting\Domain\Model\Customer 
$customer) {}

That ends up in an error that tells me that the updateAction requires a 
parameter of type HdM\Accounting\Domain\Model\Customer but 
HdM\Accounting\Domain\Model\Business(or Private)Customer has been given. 
I hoped that FLOW would automatically upcast to it's parent class but it 
doesn't. So far the only working solution I found is to write two 
update-, create- and delete-methods, that require the concrete types, 
which ends up in a lot of stupid copy/paste-work (6 more methods + 
corresponding template files). I think there should be a smarter 
solution but until now I have not been able to find it. I would be 
really content if someone had a good solution for that.

Yours
Mathis
