children component rendering without children

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I am in a situation where I want to render a component from another
component without the need for sub-composition and where I want to
prevent the use of #children.
Mainly because the parent component does not know what is rendered. Is
it possible? Or may be I have been exaggerating in the meta direction.

How is that possible? :-)

At some point a parent must initiate the rendering of its children,
otherwise that child will never be visible. So how can a parent not
know its children?

Note that you can always display renderable objects (presenters in
Seaside 2.9) without declaring them as children. Only components are
required to be declared.

It is :) But it looks like a bad hack; to write fewer lines of code.
Gonna refactor this anyway.

Hilaire,
In SmallFaces we do not use #children anymore, take a look here http://wiki.squeak.org/squeak/6088
Cheers

Re: children component rendering without children

sure. if you aren't using components (ie. you don't have state that needs persisting or the ability to update the root or url, etc), you don't need to implement #children.
