How to pass AdvanceCriteria argument using DMI from client to service method

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

How can I pass a client side AdvancedCriteria (com.smartgwt.client.data.AdvancedCriteria) via a DMI call to a service implemented using the gwt server framework.

It looks like the DSRequest parameter may be intended for this but on the server side the AdvancedCriteria retrieved from the DSRequest is of type (com.isomorphic.criteria.AdvancedCriteria) and no "magic" is performing the conversion on the DMI request.

Bottom line is I want to have an AdvancedCriteria argument on my DMI service. Problem I'm having is converting from client side (smargwt) AdvancedCriteria to a serverside (isomorphic) criteria.

Thanks
