Hi Is there a best-practise implementation of CRUD avents (Create, Read, Update and Delete) in a templatesheet for a class Default the following is generated for a XWiki class #set($class = $doc.getObject('CdlsatdCode.CdLSATEPublicQAClass').xWikiClass) #foreach($prop in $class.properties) ; $prop.prettyName : $doc.display($prop.getName()) #end This is fine for Read (=View) and Update events except for rules to be implemented around data integrity with update When I CREATE the object (test for $doc.isNew() in most cases, unless multiple objects are created on same document, this might be case for internationalization typical things to do in CREATE is setting of the defaults value, setting keys that link to other objects (child of...) When I UPDATE the object there might be attributes where we test Old.value against New.Value and NEW.Value might When I DELETE the object (or the containing document) I might want to prevent that in order for integrity (by example Parent Child relation ships, do not delete the parent while there are still childs) This is related to my previous post, since I discover the code is really becoming a mess if I do not use a best-practise Who has implemented a practise and can tell me about the pro's and con's, this might be even a good thing to publish on the documentation of XWiki.org since i expect many who are involved in building forms run into the same questions Gerritjan
