Hi ! Since few days, I work with the new XWiki (4.0). But I don't understand how XWO_ID and XWD_ID are created ? For the 3.5 version, it was the hashcode of the string obtained by concatenating the document name, the XClass name, and the object number. But for the 4.0 version... I don't really know. Can you help me ? Please. Goodbye Caroline. -- View this message in context: http://xwiki.475771.n2.nabble.com/XWiki-4-0-How-XWO-ID-and-XWD-ID-are-creat… Sent from the XWiki- Users mailing list archive at Nabble.com.
