XWiki Application Organization

This Best Practices document explains how to best organize an XWiki Application. 

Check for Object existence in Class Sheets documents

Class sheet documents should be written using the following construct (this is an example for displaying documents containing XWiki.XWikiUsers objects):

#set($obj = $doc.getObject("XWiki.XWikiUsers"))
 1 User Sheet
 This stylesheet must be applied on a document containing a XWiki.XWikiUsers object.
 1 $msg.get("userProfile", [$xwiki.getUserName($doc.fullName, false)])

The 'if' tests first for the non existence. This is so that XWiki extract the title from the 1 User Sheet, which is a proper title to display when viewsing the sheet page, instead of the computed name which will usually display something wrong.
