Import WSDL with external reference

Hi Guru.

I need your help.

I would to import this WSDL in PI:

[fwsservice.wsdl|http://archive.groundworkopensource.com/groundwork-opensource/branches/FOUNDATION_5_2_1_SP/collage/api/wsdl/fwsservice.wsdl]

but I have a problem: when I load the external definition in PI I see that it have an external reference. So I load this WSDL

[fwsmodel.wsdl|http://archive.groundworkopensource.com/groundwork-opensource/branches/FOUNDATION_5_2_1_SP/collage/api/wsdl/fwsmodel.wsdl]

and in the source field I insert the reference of the first WS

When I import in the Message Mapping the definition the node with exeternal reference are in "ERROR".

Have you some idea?

I try some ways to fix this problem (a custom data type with same namespace, modify the WSDL,..) but without good news.

Help me please

Bye

Manuel
