Integration Elfinder Connector with CKEditor

[jackfolla79]

Hello, I'm trying to call connector from CKEditor with Elfinder , editing the config.js of Ckeditor ( I follow https://github.com/Studio-42/elFinder/wiki/Integration-with-CKEditor and http://docs-old.ckeditor.com/CKEditor_3.x/Developers_Guide/File_Browser_(Uploader) )
But when I click on "Send to server" of CKEditor I have target == null

CKEDITOR.replace( 'editor1',
{
config.filebrowserBrowseUrl = '/myapp/elFinder/elfinder-cke.html';
config.filebrowserImageBrowseUrl = '/myapp/elFinder/elfinder-cke.html';
config.filebrowserUploadUrl = '/myapp/elfinder-servlet/connector?cmd=upload';
config.filebrowserImageUploadUrl = '/myapp/elfinder-servlet/connector?cmd=upload';
});

Anyone integrate elfinder in ckeditor?
thank a lots
