Hi all, has there some discussions about a name conflict, if I start to add an object to a folder with an object-id wich is also a Property of the folder ? In the method _checkId of the ObjectManager e.g. the folder is checked with hasatrr(this,id). And this is true if there exists a property with the same name as the object-id. I see no workaround, because a property or an object are attributs of the folder. Any comments ? Martin
