Web Service Configurations problem

Hi all,

I need your help because an apparently stupid problem: when I try to publish (by a web service configuration) the properties of a Relationship ItemType (es. "Program Project"), I can choose all the properties of the Relationship but the property "source_id". It's obvious that without that property, the Relationship is unusable (I cannot recover the Source Item).

So, there's something that I don't know about publishing Relationship ItemType? Maybe I can obtain that information in another way?

Thanks.

Guido
