[Ovmsdev] A query on vehicle type switch (and failure)

[Mark Webb-Johnson]

Michael,

From the condition in the v_type->SetValue, the type is only set if NewVehicle(type) is not NULL.

So the question is whether we should raise the signal or not? I guess that is debatable, and probably better not to (as otherwise it is being raised with type as the parameter, but the type is not actually being set as the vehicle type).

Regards, Mark
