My problem was that when I build the list from a hashtable I added the keys
instead of the object. ie;
list.add(key);
instead of;
list.add(hastable.get(key));
Aaaarghhh!!!!
And that's why tapestry said (quite truthfully) that it could find no method
getId() or getName() or __java.lang.Integer___ !!!
Cheers,
