For containers which are currently being rendered:
markupContainer.getMarkupStream()
markupContainer.findMarkupStream()
Note: MarkupContainer.markupStream is a temporary variable only and
only available during the render cycle.

The component you want the markup stream for has to be rendered
already. That is, you can not get the markup stream of a component
which will be rendered later. Separating the current render phase into
a attachMarkup and render phase is scheduled for wicket V2 as it most
likely requires major changes to wicket core (and will not be
backwards compatible. Chris and Jon discussed it a year ago already)
However, this is how to get a markupStream
MarkupStream markupStream =
findParentWithAssociatedMarkup().getAssociatedMarkupStream();
// Make sure the markup stream is position at the correct element
markupStream.setCurrentIndex(this.markupStreamPosition);

I don't see why.
