IIRC, autocallable methods have never been populated from the
configurable object's data. You need to use form defaults for that,
which would look something like ...
def render_edit(self, ctx, data):
defs = ctx.locate(iformless.IFormDefaults)
... etc ...
Interestingly, setting the defaults as above prepopulates *both* forms.
I think it should only populate the self.orginal form. To populate the
self.myObject form I expected to need to set the default for the
