Thank you very much for the catch!!!
I am stuck half way in D2W land. the TPMODInspectPage only knows about the
object(). I was hoping that I could just wire up a button that says "Dupe" and
the method would dupe the EO, saveChanges and present the lastPage.
Obviously, object().copy() won't work as object is an EO that doesn't know that
the method copy() exists. I don't think I should be casting this to an Entity
of Agenda as that kind of destroys the abstracting process.
I think I need to do (pseudo coded)
if (object().respondsTo(copy)) {
EO newObject = object().copy();
saveChanges(newObject().editingContext);
}
But I am tired and lost here. I have the Practical WO book at home and hope
that will shed light on my ineptitude.
