WSDL containing import of XSD fails to load

I recently added a xml schema to a WSDL deck using an import statement and now when I attempt to load the wsdl into SOAPUI (4.5) I am taking a java.io.IOException with the message "Attempted read from closed stream".

I am thinking there must be some setting within soapUI to allow this kind of construct in the WSDL deck but, after poking around, have not been able to find anything. I can't seem to find a similar problem posted anything on this (or other) boards.

Anyone ?

Thanks
