Passing Criteria in RPC-DMI call

v9.1p_2014-03-18/Pro Deployment (built 2014-03-18)

I would like to pass a client side AdvancedCriteria via RPC-DMI to a server side method.

Isomorphic documentation at http://www.smartclient.com/smartgwtee/javadoc/com/smartgwt/client/docs/DmiOverview.html has an example of passing arguments using RPC DMI. That's exactly what I need but require an argument of AdvancedCriteria type be added to the method signature.

Can you tell me how to go about this ? I cant figure out how to handle the serialization/deserialization/conversion from client side to server side representation of the AdvancedCriteria argument ?

Thanks
