> A DeltaView cannot be installed because the ref view-id is not the current view-id.

> K cannot install DeltaView J|3 because it has view J|2 but the DeltaView has ref view-id J|1.
> The reason is that J|2 was apparently installed *only* at K (but not at coordinator J1!), despite it being the same view as J|1.
> We need to look into why J|2 was installed at K only. Second line of defense: when a DeltaView cannot be installed, send a message to the view sender (coord) and solicit the full view instead.
> See the attached log.
