11924	Uncaught TypeError: Cannot read property 'hasAttribute' of undefined	Catalin		"Hi,

I'm working on a project and we are using CKEditor 4.3.2.
I have a test where each question is displayed in a new html page. But when i switch from one page to another i get the error ""Uncaught TypeError: Cannot read property 'hasAttribute' of undefined"".

I did some debug and i saw that this happens because the previous editor instance from the previous page (it has the same editor id) is still listening (although destroyed) to the ""customConfigLoaded"" event. So i guess it's catching the custom loaded config event in the new page.

And at the line:
{{{
a.readOnly = !(!c.readOnly && !(a.elementMode == CKEDITOR.ELEMENT_MODE_INLINE ? a.element.is(""textarea"") ? a.element.hasAttribute(""disabled"") : a.element.isReadOnly() : a.elementMode == 
                CKEDITOR.ELEMENT_MODE_REPLACE && a.element.hasAttribute(""disabled"")));
}}}
a.element is null because the editor was destroyed and a.status is ""destroyed"".

From what i could tell also, this listener is not removed in the removeAllListeners method, i see it's not part of the list of events to be removed.

Is there any way i can solve this without modifying the ckeditor code ? I have tried a lot of things but nothing seems to work.

Thanks,
Catallin"	Bug	closed	Normal		General		duplicate
