Ref (table) parameter RFM .net Connector 2.0

Hi to all, I am using .net connector 2.0 in a web application, I have create a RFM that have a export parameter and a table parameter, in Sap I execute the function a return values in the export parameter and in the table but .net the export parameter return value but the table is empty.

Have I to customize something in the proxy object for get values in ref parameters?

I have no problems with the import and export parameter but I can not get the table values and I am sure that in Sap have values.

Thanks in advance.
