Thanx for the pointer. Regarding the schema, I think my approach is
ok. "add" is part of the public API of a SchemaNode, and order in the
schema doesn't matter. Order does only matter for the rendering of the
Form, so my question is more related to my messing with Form.children.
I also want to manipulate the already instantiated Form, so the
self.children = []
self.__dict__.update(kw)
for child in schema.children:
self.children.append(Field(child,
renderer=renderer,
counter=self.counter,
resource_registry=resource_registry,
**kw))
in Field.__init__ has already taken place (and so manipulating the
order in the schema doesn't help anymore). I guess my question boils
down to whether I can regard the "children" list on deform.Field as
public API.
