Hi,

The story starts here : http://ez.no/developer/forum/install_configuration/is_it_possible_to_browse_by_node_id/

Since this modification not done yet, I wrote this datatype based on another datatype (I don`t remember which one).

this DT will create random number which can be used for url_alias, thats all ... I think there is many mistakes ... can you check it ?
