actually, scratch that last idea about setModel... for a complex
component, this won't work.
how about this? we have a guaranteed ordering for components in a
container and
then we provide this:
/**
* Sort children using comparator
*
* @param comparator
* The comparator
*/
public void sort(Comparator comparator)
{
if (children instanceof Component[])
{
Arrays.sort((Component[])children, comparator);
}
}
doesn't expose any implementation details and lets you reorder the children.
would that make you happy?

If we don't guarantee the order I think we should at least introduce two
template methods: onChildAdded(Component) and onChildRemoved(Component).
These would be called from the add(), remove(), removeall(), etc.
Right now you need to look at the internals to know that autoadd() calls
add() internally, removeAll() doesn't call remove() for every object, etc.
Having onChildAdded and onChildRemoved will make it easy to add your own
ordering logic.
Also making iterator() overridable will further facilitate a
user-implemented ordering at render time, although this might open a can of
worms.

Subject: Re: [Wicket-develop] [ wicket-Patches-1260172 ] add
getchildren to markupcontainer
a good question. we should add it to the javadoc if it's
true. i think we should at least guarantee that
FormComponents are validated in the order they are added.
more than that, i'm not so sure.

On a side note,
Is the fact that iterator() now returns items in the order they were
added going to be a formal contract?
