Problem importing WSDL

Hi -

I am building a call to an external webservice. I was provided from an WSDL from an external vendor.

The problem is that when I import it in PI as a new External definition into a Namespace, I do not get the Messages populated.

I tested using the WSDL in both SOAPUI and Eclipse and both are able to open it and generate the WS calls.

Any clue on what can be happening?

Thanks in advance !!!

Carlos.
