Running from zope, you will need to modify this connector.
If you have uploaded the FCKeditor into Zope (like me), you need to
move this connector out of Zope, and replace the "connector" with an
alias as below.  The key to it is to pass the Zope context in, as
we then have a like to the Zope context.
