What am I doing wrong here ... please !! I am trying to make an autoincrementing counter for use in a diskussion forum. It's purpose is to autogenereate id's for new messages. It is important that the id's are in order, so I need to make them this way. I have a zClass (objectmanger) with a property called "lastID", on a propertysheet called "hidden". I have then written a dtml mehtod that should return the id incremented by 1 and then sets the lastID to this new id. the dtml for the "newID()" dtml method looks like this: ---------- <dtml-call "REQUEST.set('new_id', lastID+1)"> <dtml-call "REQUEST.set(lastID, new_id)"> <dtml-return "_.int(new_id)"> ---------- When I try to get the property directly via the browser i get a result of "1" The default value for lastID=0 to begin with so this sounds plausible, but when I refresh the browser nothing happens. So I guess that lastID isn't updated in the above code. How do I do that? Also when I the try to insert "newID()" in my "mxm_comment_add" method in my zClass, to autogenerate numbers, like this: <dtml-with "mxm_comment.createInObjectManager(newID(), REQUEST)"> I get the following traceback: (And I would expect it to run at least 1 time with "1" as a new id.)
