when sent a message, the target can't find itself!

The more I think about it, the less I think "the target" is what you 
want. The target is the the first object to receive a message in a 
sequence of events; in this case the field is not receiving any 
messages, it is generating them.

Instead of having the generic handler try to figure out the object 
reference, it should receive it in a parameter. The field should call 
the handler using something like this:

   doAdd the long name of me

The generic handler then does this:

   on doAdd pFldLongName
     put the value of pFldLongName + 45 into pFldLongName
   end doAdd
