Custom Stored Procedure Returns void - Tips/Tricks - Support Forums

We are using Codesmith 5.2 and Nettiers templates to generate a method from a custom stored procedure.
The stored procedure name is 'usp_Participant_SearchParticipantAddress'. There is a table by the name 'Participant' in our database.
The method gets generated correctly on the ParticipantProvider but the return type of the method is void instead of dataset.
The stored procedure is:

The stored procedure should return a dataset because we are doing a select statement on a view that joins multiple tables. We are using SQL 2008 
Enterprise Edition.

How can we get Nettiers to return a dataset?

Please help. Thanks in advance.
