SmartObject execution error.

I wanted to also add myself to the list of those experiencing this exception (Exception of type 'SourceCode.SmartObjects.Client.SmartObjectException' was thrown.).  I haven't found a solution to it.  In my case, the code snippet below is trying to execute a "List" method that is referenced by the "Broker" smart object.  The implementation of this List method is done via a custom smart object service instance that I successfully configured in the BrokerManagement app on the K2 server.  I also able to successfully reference the service's method from the Broker smart object method wizard in the designer.  No compile time errors.  Any ideas on how to troubleshoot?  Thanks.

 server.CreateConnection();
 server.Connection.Open(connStr.ToString());

 SmartObject smartObject = server.GetSmartObject("Broker");
 smartObject.MethodToExecute = "List";

 SmartObjectList smoBrokers = server.ExecuteList(smartObject);   // throws exception on this line

 foreach (SmartObject smo in smoBrokers.SmartObjectsList)
 {
         Broker b = new Broker();
         b.ID = Convert.ToInt32(smo.Properties["ID"].Value);
         b.Name = smo.Properties["Name"].Value;
         brokers.Add(b);
 }

Hi Guys

So I was having the same problem as you all.
I implemented the following catch clause after the executescalar being in the try section of the clause.

catch(SmartObjectException soEx) {

StringBuilder sb = new StringBuilder();

foreach(SmartObjectExceptionData soExData in soEx.BrokerData) {

sb.Append("Service: ");

sb.AppendLine(soExData.ServiceName);

sb.Append("Service Guid: ");

sb.AppendLine(soExData.ServiceGuid);

sb.Append("Severity: ");

sb.AppendLine(soExData.Severity.ToString());

sb.Append("Error Message: ");

sb.AppendLine(soExData.Message);

sb.Append("InnerException Message: ");

sb.AppendLine(soExData.InnerExceptionMessage);

throw new Application Exception(sb.toString(), soEx);

}


This will give you the actual error that the smartobject is returning. Mine was a datetime value being in the wrong format.
so if you selected a date lower than 12 it worked, anything higher and it failed as obviously there are only 12 months in a year ;)

I hope this helps some people!
