That problem went away when I upgraded to jsf-1.2_02 (I think). My 
temporary workaround was to clear the hidden parameter manually with 
javascript - although better if you can find a permanent fix.

      $('fb-navigator')._submit = $('fb-navigator').submit;
      $('fb-navigator').submit = function() {
 
this['fb-navigator-tree:org.apache.myfaces.tree.NAV_COMMAND'].value='';
          this._submit();
        }
      };

(replacing fb-navigator the id of your form and fb-navigator-tree with 
the id of your tree2).

 > Has anybody had success using basic h:commandLinks with ie as a part 
of a tree2 facet? When I try, it looks like ie is POSTing 
org.apache.myfaces.tree.NAV_COMMAND=null and this causes a 
NumberFormatException on the server:
