Access Denied error on IE7 and IPv6

[Damian]

We are testing the editor in an IPv6 environment on IE7.

Script debugger reports the error at:

return i&&new g(i.contentWindow.document);

in ckditor.js. This looks to be in issue in element.js.

I suspect it is the call to contentWindow.document that is causing the "Access Denied" error.

The editor loads, but is not usable.

Works well with IE8, in all modes.

WFM in IE7, with both IP and normal domain name.

Proposed fix

[Damian]

The added patch indicates the problem.

In IE7 document.domain = "[fe80::fe80:fe80:fe80:fe80]"
and window.location.hostname = "fe80::fe80:fe80:fe80:fe80" (i.e. no brackets [] )

This difference is causing isCustomDomain() to return true when in fact it should return false.

@damo, wonderful job. thanks for the patch.

I've provided a new patch, based on your code, which should produce a more compact output. Please give us the last ok for it, so it'll get approved and committed. Thanks!

Thanks Fred! The proposed fix works.

One side note here is that the user must add the host to their list of trusted sites in IE otherwise the "Access Denied" error will still occur. There doesn't seem to be any way around this.

Fixed with [5407].
