Problem with external reference importing wsdl definition

Hi experts.

We're facing some problems importing a wsdl file provied by a client.

We've imported the wsdl file as external definition and we've imported the referenced xsd files in the same namespace.

One example:

In wsdl file we have:

<s:import schemaLocation="http://xx/Afine/GestionIncidencia.BS/webservices/gestionincidenciaws.asmx?schema=GeServicioVis" namespace="http://xxx/GeServicioVis.xsd"/>

We've imported the xsd from shemaLocation as an external definition and we've populated "Source" field with this schemaLocation.

Now in "External Reference" tab I can see the "Name" column populeted and I can navegate to the external definition but I can't see the estructure populated in the main message in tab "Message" neither in a message mapping.

¿Any idea what could be wrong?

Thanks a lot.

Best regards.
