Re: NPE at InterfaceCacheDefinitionLoader

I generated a WSDL from another application and tried to start a new SOAPUI project using the WSDL. If I used the WSDL URL to import the WSDL to the project, then I got a NPE at InterfaceCacheDefinitionLoader. However, if I save the WSDL file locally on my desktop and then import it into my SOAPUI project, then I have no problems in creating a project. I can easily access the WSDL from the browser using the WSDL URL so there are no problems with the URL returning blank.
Any advice?
Thanks
