John, you are getting confused between a property that refers to an object, and a contained object.

If you created a form property called oClass and then made it a reference to an object using, CREATEOBJECT, you have not added a member to the form, you have created an object and set the form's property as a reference to it. If you want the object to actually be a member of the form, you should use

THISFORM.Addobject('oClass', 'ClassName')
