jsTree copy_modifier：false - 不會阻止節點複製！

Question

這是我的代碼，它應該在使用ctrl鍵時防止節點複製，但它仍然允許複製並且不會阻止它。

根據文檔我使用"copy_modifier" : false - 任何想法爲什麼它不起作用？

我使用穩定版本"jsTree 1.0-rc3"只是幾天前通過網站上的大下載按鈕下載。

$(function() { 

    $("#jsTree") 
     .jstree({ 
      "plugins" : ["themes","html_data","ui","crrm","hotkeys","types","dnd","contextmenu"], contextmenu: {items: customMenu} 
      //"core" : { "initially_open" : [ "node_root" ] } 
     ,"types" : { 
      "valid_children" : [ "group","unknowngroup" ], 
      "types" : { 
       "group" : { 
        "valid_children" : ["event"], 
        "start_drag" : false, 
        "move_node" : false, 
        "delete_node" : false,

       commitGroupRename(data.rslt.obj.attr("id").substring(11),data.rslt.new_name); 
       var text= prefix + data.rslt.new_name; 
       $("#jsTree").jstree('rename_node', data.rslt.obj, text); 
       prefix="";

      if ($(node).attr('rel')=="group" && prefix =='') 
      { 
       var text = $("#jsTree").jstree('get_text',node); 
       prefix = text.substring(0,5); 
       text = text.substring(5); 
       $("#jsTree").jstree("rename_node", node , text); 
       $("#jsTree").jstree("rename",node); 
      } 
     }).bind("select_node.jstree", function (node, ref_node) { 
      var theRealNode = $.jstree._focused().get_selected(); 
      if (theRealNode.attr('rel')=="group") 
      { 
       $('#btnRenameSelected').attr("disabled", false); 
       $('#btnRenameSelected').removeClass("ui-state-disabled"); 
      } 
      else 
      { 
       $('#btnRenameSelected').attr("disabled", true); 
       $('#btnRenameSelected').addClass("ui-state-disabled"); 
      } 
      }); 
});

固定 - 正如你可以看到「dnd」實際上在「types」範圍內。衛生署！ - 如果允許，將接受。
