    I think it's happening only because Chrome and IE implement some standards in different ways. I also have this error, but feels like it's doesn't lead to any real problem.

    Actually, i found that this happens on Chrome, if i use IE then there is no error. I also realise that there are lots of javascript errors if i use other browsers instead of IE.

    Hi Mehmet,

    What browser are you using? Are you experiencing this behavior on IE 11?

    If you are using Google chrome what is the version number?

    Thanks.

    Hi,

    Have you written an XML request in the Javascript library registered in the form? It can lead to this error.

    Hope this helps.
