Finding Presentation Input Parameter Properties

I am using the VCO SDK with orchestrator 5.1.0 build 2725.  I am needing to access the Presentation Properties.  In particular I am looking for the Default value for each presentation item.  I use my workflow to retreive my a presentation object. From it I retreive the input parameters but for every input parameter the properties attribute is null.  Should this be populated with the property values for the presentation item?

Here is a piece of code I am using to try to look at the properties:

private static void checkPresentation(Workflow wf) {
        PresentationService ps = new PresentationService(session);
        Presentation pres = ps.getPresentation(wf);
        com.vmware.o11n.sdk.rest.client.stubs.Presentation.InputParameters ip = pres
                .getInputParameters();
        List<Parameter> parmList = ip.getParameter();
        for (Parameter parm : parmList) {
            com.vmware.o11n.sdk.rest.client.stubs.Properties parmProperties = parm
                    .getProperties();
            if (parmProperties != null) {
                List<KeyValuePair> propList = parmProperties.getProperty();
                for (KeyValuePair aProp : propList) {
                    System.out.println("Input Parameters Key: "
                            + aProp.getKey());

                }
            }

        }
    }
