Programming rights in notify

Hi all, I have a plugin that does stuff requiring programming rights. For example it calls Document.getDocument(). This is fine: the plugin is invoked from a doc saved by someone with prog rights. The plugin API is passed the XWiki API object obtained when that document is parsed. So I can then use that to do: wiki.getDocument(blah).getDocument(). Now I need to do something similar when a document is saved, rather than when invoked by the user. So I'm implementing XWikiDocChangeNotificationInterface.notify(). However I don't know how to get an XWiki API object that will return true for checkProgrammingRights() from my notify implementation. Assuming this makes sense, does anyone have any ideas? :) Regards, Robin
