[xwiki-users] How to add multiple objects to a page

In the dev guide, there is a description, how to add a single object to a page (http://platform.xwiki.org/xwiki/bin/view/DevGuide/APIGuide#HAddobjectstoapag...). Unfortunately, adding multiple objects does not work this way. Is there any example how to do this? Thank you in advance, Matthias
