hello i have this error : TypeError: this.getWindow(...).$ is undefined in ckeditor.js: line 83

i am trying to ajaxify comments in drupal but this error occures when i reply a comment and i try to save.

this is my code: $.ajax({

type: "POST", url: url, data: $(this).serialize(), serializes the form's elements.

success: function (data) {

document.title = data.match("<title>(.*?)</title>")[1];

data = $(data); var link = [],

style = [], script = [];

var currentLink = $('link'),

currentStyle = $('style'), currentScript = $('script');

for (var i=0; i <data.length; i++) {

switch (data[i].tagName) {

case "LINK":

link.push(data[i]); break;

case "STYLE":

style.push(data[i]); break;

case "SCRIPT":

script.push(data[i]); break;

}

} link = $(link), style = $(style), script = $(script); getNewElement(link, currentLink); getNewElement(style, currentStyle); getNewElement(script, currentScript);

$( "#content" ).html( data.find("#block-system-main")); Drupal.attachBehaviors('#content');

var content_type=Drupal.settings.ajax_links_api.class_content_type; $("body").attr('class',content_type +' toolbar-drawer');

ajaxLoading = false;

getCurrentCatForBody();

}, error: function (xhr, ajaxOptions, thrownError) {

window.location = url;

}

});

I'm not familiar with such problem and it looks to me like an implementation issue.

Could you please provide reduced application showing this problem in code? Best if it is some external URL to zipped project that I can drop into my server and check problem locally.
