The correct status is set by cu_validate_ref() and directly returned to the client. So this is not necessary here. -- Regards Heidi Eckhart Software Engineer IBM Linux Technology Center - Open Hypervisor

That's a very good point ! I was too inattentive when patching the association providers. -- Regards Heidi Eckhart Software Engineer IBM Linux Technology Center - Open Hypervisor
