與TinyMCE的4集成elfinder，「類型錯誤：parent.tinymce.activeEditor.windowManager.getParams不是一個函數

我還是新手整合elfinder和TinyMCE的，我已經跟着教程elfinder wiki 與TinyMCE的4集成elfinder，「類型錯誤：parent.tinymce.activeEditor.windowManager.getParams不是一個函數

在form.php的在TinyMCE的初始化已經添加file_browser_callback：elFinderBrowser：

tinyMCE.init({ 
       mode : "exact", 
       elements : "txt_content", 
       theme : "advanced", 
       file_browser_callback : elFinderBrowser, 
       plugins : "advimage,advlink,media,contextmenu", 
       theme_advanced_buttons1_add_before : "newdocument,separator", 
       theme_advanced_buttons1_add : "fontselect,fontsizeselect", 
       theme_advanced_buttons2_add : "separator,forecolor,backcolor,liststyle", 
       theme_advanced_buttons2_add_before: "cut,copy,separator,", 
       theme_advanced_buttons3_add_before : "", 
       theme_advanced_buttons3_add : "media", 
       theme_advanced_toolbar_location : "top", 
       theme_advanced_toolbar_align : "left", 
       extended_valid_elements : "hr[class|width|size|noshade]", 

       paste_use_dialog : false, 
       theme_advanced_resizing : true, 
       theme_advanced_resize_horizontal : true, 
       apply_source_formatting : true, 
       force_br_newlines : true, 
       force_p_newlines : false, 
       relative_urls : true 
     });

，並添加功能elFinderBrowser太：

function elFinderBrowser (field_name, url, type, win) { 
    tinymce.activeEditor.windowManager.open({ 
    file: 'elfinder.html',// use an absolute path! 
    title: 'elFinder 2.0', 
    width: 900, 
    height: 450, 
    resizable: 'yes', 
    inline:true 
    }, { 
    setUrl: function (url) { 
     win.document.getElementById(field_name).value = url; 
    } 
    }); 
    return false; 
}

      }, 
      mySubmit: function (URL) { 
       // pass selected file path to TinyMCE 
       parent.tinymce.activeEditor.windowManager.getParams().setUrl(URL); 

       // close popup window 
       parent.tinymce.activeEditor.windowManager.close(); 
      } 
      } 

      $().ready(function() { 
       var elf = $('#elfinder').elfinder({ 
        url : 'connector.php', 
        getFileCallback: function(file) { // editor callback 
         // file.url - commandsOptions.getfile.onlyURL = false (default) 
         // file  - commandsOptions.getfile.onlyURL = true 
         FileBrowserDialogue.mySubmit(file); // pass selected file path to TinyMCE 
         } 
       }).elfinder('instance'); 
      }); 
     </script> 

    </body>

，但是當我在elfinder窗口中選擇/選擇圖片，它顯示firegbug錯誤：
