Ext Htmleditor readOnly js error

[HTK]

My ExtJs 4.1.2 HtmlEditor throws an javascript error instantiating it with readOnly: true.

NS_ERROR_FAILURE: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMHTMLDocument.execCommand] 

Somebody here who knows what causes this error ?

This is working for me in 4.1.2 and 4.1.3:

new Ext.form.Panel({
    renderTo : document.body,
    items    : [
        {
            xtype      : 'htmleditor',
            fieldLabel : 'Test',
            readOnly   : true
        }
    ]
});

Then maybe it´s anywhere else in the code. Our company is working on a CMS, so it´s too complex to post code here. I´ll have to debug myself. Thank´s for answering.
