I'm seeing some strange behaviour when attempting to add a VM network (eg a HostNic) to a reservation (eg a cluster).
On the one hand, I am receiving errors from VCAC when I create the HostNicToReservation entity (specifying only HostNicID and HostReservationID as normal properties).

On the other hand, the relationship shows up in the vCAC GUI and seems to have been correctly created.
I've done the same excersize from powershell, using the function call "AddToHostNicToReservations", which works great.
