Can you post an section of your code? The method to Execute should work, however, you would need to call one of the ExecuteList methods provided on the API. He is a code snippet where I have wrote a SmartObject execution engine and check to see if the method I am executing is a list or not and handle appropriately.

var results = new SmartObjectList();

var isList = false;

isList = (from SmartListMethod m in smo.ListMethods
where m.Name == smo.MethodToExecute
select (true)).FirstOrDefault();

if (isList)
results = SmoServer.ExecuteList(smo);
else
results.SmartObjectsList.Add(SmoServer.ExecuteScalar(smo));

The part you are missing is most likley the ExecuteList. You can also validate that you are using the right method name by checking the SmartObject tester tool and viewing XML. There is an unrealized gotcha that gets a lot of people as the name you read (Display Name) isn't always the same as the name that K2 uses to execute the call (System Name).

Hope this helps.
