Facing javascript error "Invalid argument" in IE 7 and IE 8 in the xforms-dialog-yuicalendar-min.js

Hi,

I am facing the following javascript error in IE 7 and IE 8 whenever trying to access Orbeon form builder by the url "http://localhost:8080/orbeon/fr/orbeon/builder/new". I am using Orbeon 3.7.

Message: Invalid argument.
Line: 26
Char: 1374
Code: 0
URI: http://localhost:8080/orbeon/xforms-server/xforms-dialog-yuicalendar-min.js

Can anyone have idea about this, so please give me response.

Thanks,
Nitin Agarwal
