I need to know if is possible to have, in a class definition, a numeric attribute which is filled with the id of the object at the moment of the object creation automatically. So when an object is created from a user the attribute automatically gets the id of the object (which is unique) and I can also use it for the Object Name Pattern to name the object created. Do you think is it possible? I really need to know it. Thank you

I think it can be realized with a code that fetch the object id, then I need to put this value into an attribute (not editable from users). Something like the User Account datatype. Someone can tell me an idea on how to realize it? Thanks a lot.
André R.	Tuesday 01 April 2008 3:38:40 am create a simple datatype that just stores the object id in an attribute ( not if you use node id: the object doesn't necessary have a node ). Or use a int attribute and override the edit template of it for that particular attribute identifier, where you set the id in a hidden input box (again note that object might not have a node id). I'm not sure why you need this though, since you can always get the node id / object id by code. template: {def $obj_id = $my_object.id $node_id = $my_object.main_node_id} $node_id will be 'null' if the object doesn't have a node. eZ Online Editor 5: http://projects.ez.no/ezoe \|\| eZJSCore (Ajax): http://projects.ez.no/ezjscore \|\| eZ Publish EE http://ez.no/eZPublish/eZ-Publish-Enterprise-Subscription @: http://twitter.com/andrerom
christian bencivenni	Tuesday 01 April 2008 11:57:57 pm Sorry I made a mistake in my second post. I always mean OBJECT id (not node id). The scope of the attribute is simple: I had to add a unique identification code automatically in the object name at the moment of creation but I don't want to store all the codes in a db table and implement function to search, test and store codes. So I thinked to use the object id which is already unique. The only problem for me is to assemble a datatpe which made the job and is invisible to the user, and use it to generate the Object Name Pattern in the class definition. Do I have other options? Is it possible to define the Object Name Pattern with the object id without create a persnalized datatype?
