Hi Matthias, If you wish to modify the rendering of a document at runtime without changing its content you can: * Use a Sheet binding, see http://extensions.xwiki.org/xwiki/bin/view/Extension/Sheet+Module. That’ll allow to add stuff before and after the document’s content. That’s the simplest. * Use a Transformation, see http://rendering.xwiki.org/xwiki/bin/view/Main/Extending#HAddinganewTransfor...

Hi All,

i want to put a {{warning}} in the header of a page when a specific macro is not contained. How can i do that. I tried in a Listener when the needed Macro-Block is not contained with

doc.getXDOM().getRoot().addChild(new WordBlock("{{warning}}Warning Text.{{/warning}}")); context.getWiki().saveDocument(doc, context);

This not works. What is the correct way to manipulate the Document DOM on Load?
