Sorry, I misunderstood you.

Right; I see what you mean.  I'm wondering if maybe I should just add 
'viewHandler' to the list of attributes that are automatically cloned.  But 
I'm not sure if there are maybe clonings that change 'current', but where 
the viewHandler should *not* be kept.  I'll have to take a look at that.
