I need it because I am using the xwiki for tracking bugs and errors for a external development. I goes quite good. And to get a unique identifier for every "bug" created. How can I get some code executed in one of the properties of the class, so the property get's the value you mentioned?

I don't think there is "built-in" ... But if you manage the process of creation of objects, you can code the autoincrement yourself (for example searching last value from most recent object then incrementing for new object). What do you need this for ?

Thanks. -----Mensaje original----- De: users-bounces(a)xwiki.org [mailto:users-bounces@xwiki.org] En nombre de Jeremie BOUSQUET Enviado el: miércoles, 24 de febrero de 2010 11:16 Para: XWiki Users Asunto: Re: [xwiki-users] Autoincrement value in class Well, You can't execute code directly in a class property, you have to manage this code at object creation time. I see another possibility, if your matter is only that the Id should be unique, you can directly use the Id of the object as Id of your bug. In a HQL request it would be merely a "select obj.id from BaseObject obj where ..." to retrieve the ids of the bugs, and you would not have to manage this id at all. If you really need the bugs ids to be consecutive, and you have a property "bugid" in your class, you can use something like the following to retrieve last id before creating a new bug : {{velocity}} #set($sql="select max(ints.value) from IntegerProperty ints where ints.name ='bugid'") #set($max=$xwiki.search($sql)[0]) {{/velocity}} Then increment and use it to set value for 'bugid' in object to create. You could also imagine adding all bug objects to the same xwiki documents, and Ids will directly be the number of the object. But this might not be very efficient if you have a large number of bugs in the system. Of course I admit you programmatically create the new bugs in a page using $doc.newObject(...). And it could be a good idea to check the range of possible ids and check the max is not reached ;) Jeremie 2010/2/24 Hernández Cuchí, Francisco Ricardo <francisco.hernandez(a)oepm.es> _______________________________________________ users mailing list users(a)xwiki.org http://lists.xwiki.org/mailman/listinfo/users ********************************************************************************************** IMPORTANTE: El contenido de este correo y ficheros adjuntos es confidencial y está dirigido únicamente para el destinatario/s.
