Russ,

You cann not ADD OBJECT with an empty object, because it's empty. This means none of the EVENTS and PROPERTIES that need to be called are available. A empty object could only be used via an property of the containing object

o=CREATEOBJECT([bizob])

DEFINE CLASS bizob as custom
 PROCEDURE Init
  THIS.ADDPROPERTY('data',NEWOBJECT('EMPTY'))
 ENDPROC &&Init
ENDDEFINE

, so it's not realy "contained". That means you can not use .Data.PARENT and will not be within .OBJECTS.

Up until now I had been setting up a property in my business class and using SCATTER TO NAME to turn it into an object. I have a situation where this is not desirable now, and I want to define my data object explicitly...and I don't want any properties except those that correspond to fields in my table.
