problem with creation of observation in a different transaction than the one where reservations has been claimed

[GohuHQ]

My use case is the following:

• Reservations have already been claimed and operations planned
• In my case, i need to execute some observations at different moments of my scenario and observations are designed to be created as done that's why they are not included in the planned operations.

The error raised is the following:
Model.Wms.Operation.Observation: Cannot create for (id=6799, type=(id=19659, code=\'XXXX\')) because their PhysObj are reserved <Model.Wms.Reservation(physobj=<Model.Wms.PhysObj(id=6799)>, physobj_id=6799, quantity=1, request_item=<Model.Wms.Reservation.RequestItem(id=186)>, request_item_id=186)>, which does not not agree."

I think maybe we shouldn't check if the transaction is allowed when we create an Operation.Observation.

I hope that's understandable.

What do you think @gracinet ?
