IE problems with YUI.

Hi.

Some Backstory:
We have some forms that are linked to using iFrame.

Initially opening the form in IE9 has no ill effect but when trying to access any input filed i get an error:
[No error message provided.]
oxf:/ops/xforms/xforms-server.xpl
55
65
reading processor output
name → response
id → xforms-response
<p:output name="response" id="xforms-response"/>

The debugger says
SCRIPT70: Permission denied
orbeon-989e5dc65fbc1e4e6e17606734ac9b25779353fa.js, line 16 character 1684

Whilst not explicitly stating, i believe this is a problem with orbeon creating an iframe using the YUI library and i want to disable that, can someone help with how i go about doing that?
I've tried to run javascript to remove iframe from the dom in each application firing on
xforms-model-construct.

Also if this i'm wrong in the diagnosis i'd very much like to hear about it.

Some additional information.

Since the parent site opens the orbeon forms as an iFrame.
IF i visit the orbeon form url (in another tab or whatever) and enter any input field and then go back to the page containing orbeon form as iframe, everything is fine.

Is there any way to exploit this?
