CkEditor - Uncaught TypeError: Cannot read property 'getSelection' of undefined

Question

I am implementing the CKEditor in my app. When I am trying to instantiate CKEditor to the textarea I am getting following error

Cannot read property 'getSelection' of undefined

at below line of ckeditor

getNative: function() {
 return void 0 !== this._.cache.nativeSel ? this._.cache.nativeSel : this._.cache.nativeSel = B ? this.document.$.selection : this.document.getWindow().$.getSelection() }

Any help is much appreciated.

Solution

1. I have a list of articles.
2. every time I clicked on any article a "dialog / modal" should be open.
3. in such dialog or modal there was a ckeditor element for the content of my article.
4. when I clicked on the first it worked like a charm.
5. the problem was after clicking on the 2nd, 3rd, 4th etc.

Then I started to have this error.

    TypeError: Cannot read property 'getSelection' of undefined
    at CKEDITOR.dom.selection.getNative (ckeditor.js:448)
    at new CKEDITOR.dom.selection (ckeditor.js:446)
    at a.CKEDITOR.editor.getSelection (ckeditor.js:443)
    at new CKEDITOR.plugins.undo.Image (ckeditor.js:1182)
    at CKEDITOR.plugins.undo.UndoManager.save (ckeditor.js:1177)
    at a.<anonymous> (ckeditor.js:1173)
    at a.n (ckeditor.js:10)
    at a.CKEDITOR.event.CKEDITOR.event.fire (ckeditor.js:12)
    at a.CKEDITOR.editor.CKEDITOR.editor.fire (ckeditor.js:13)
    at a.setData (ckeditor.js:275)

The solution for me was easy, tell the computer to destroy the ckeditor instance when the dialog / modal is closed. easy!.. Now is working like a charm =)

           $mdDialog.show({
             parent:      parentEl,
             targetEvent: $event,
             templateUrl: '/md-templates/blog-article.html',
             controller:  DialogController,
             scope:         $scope,
             preserveScope: true,
            onRemoving: function (event, removePromise) {
                if (CKEDITOR.instances.body) CKEDITOR.instances.body.destroy();
            }
        });

I used your code successfully, except for whatever reason, it worked much better inside of $(document).ready()
