Hello,
i need help with a problem. 
I have orchestation where I consume a Web service. In the orchestation I hav
e a 'Construct Message Shape' and two xml schemas.

The second schema is defined in web service.

The first schema is defined in my Biztalk Solution and is composed by any el
ements plus the first schema.

In the orchestation i have a contruct shape in a loop where I use xpath expr
esión to split a message(based in first schema) in several messages(based in
 second 'web' schema)

When the message is completed I call to the asp.net web service with this se
cond web message like parameter.

But when I start the orchestation do not nothing and  i find this error in E
vent Log:

Tipe: XLANG/s 

Description: You must to implement the method Add(System.Objetc) in LemonaSc
hemas.webservices.WSIncidenciasNomina_.ImportarIncidencias_request  because 
it inherits from IEnumerable.

The asp.net Web service not is invoked(the IIS´s logs are in blank)

What is the problem?
I attach the two schemas and the class that is representing the second schem
a in the webservice.

regards and thanks,

Israel Andrés.
