Hi,
I'm using CK in an iframe of a website and that works great. Except when in IE9 (IE8 maybe too not tested yet) and when compatibility mode is on. Some users complained about it.
The error is: script438 object doesn't support property or method.
Line 58, column 377: this.type!=CKEDITOR.NODE_ELEMENT&&(b=this.getParent());
When i look in the non minified code its the isReadOnly: function() of core/dom/node.js.
When in compatibility mode and the editor is not in a iframe, it works without errors.
Is there a workaround? I need to use the iframe else i have to rebuild the whole application.
