dont use a compound model, that is just a shortcut for common cases. create a model that keeps an index and a ref to the list model, and pulls things in and out like that.
class indexedmodel implements imodel { private final imodel list; private final int index; getobject() { return list.getobject().get(index); } setobject(object o) { list.getobject().set(index, o); } detach() { list.detach(); } } and pass one of those to the dropdownchoice -igor On 8/4/07, Tauren Mills <[EMAIL PROTECTED]> wrote: > > Hello, > > I have a process that reads a CSV data file.
