I have tried to use the "Proxy Settings" in SoapUI in both 4.6.4 and 5.0.0, but without success.
When I try to load a WSDL with imports, I am prompted with an "NT Authentication" window, even though I have entered username/password in the proxy settings.
After entering the correct password and username, I get a message saying:
"Error loading [the xsl url]: org.apache.xmlbeans.XmlException: org.apache.xmlbeans.XmlException: error: Unexpected element: TAG_END"
I have tried with different .xsl files, but with no luck. I have also tried with different combinations of domain/username during authentication.
