This isn't intended usage - if the $object is an RDO instance the  
assumed use case is that either you're calling $rdo_instance->update()  
which is calling the mapper internally, or you've already updated the  
rdo object before calling the mapper object yourself. What use case do  
you have for interacting directly with the mapper this way?

(Also, the patch allows bypassing any validation done in the RDO  
object's __set method - also a problem when you just pass in an id  
directly, but no need to compound that.)
