Glad to have caught this early. Here's a good question for you... I'm using (for now) an ArrayList<lookup_type_object>() to store my lookup objects. This seemed like the best vehicle and iteration was as easy as looking in the API docs. Is there a better vehicle for storing an indeterminate number of *objects* which allows for easy addition, removal and iteration? -- **************************************************************** * Usenet Impovement Project http://nacs.dyndns-office.com/usenet ****************************************************************
