How to get Vdc storage profile information where catalog located.

Hi all,

I have some catalogs in organization. ( Windows, Linux etc...).  I want to get the Vdc storage profile information where catalog located.

var reference = catalog.toAdminObject().catalogStorageProfiles.vdcStorageProfile;
var storageProfiles = vdcHost.getEntityByReference(VclFinderType.VDC_STORAGE_PROFILE, reference);
System.log(storageProfiles.name);

System.log(reference); returns " DynamicWrapper (Instance) : [VclObjectList]-[class com.vmware.vmo.plugin.vcloud.model.VCloudExtensibleListDecorator] -- VALUE : com.vmware.vmo.plugin.vcloud.model.VCloudExtensibleListDecorator@35ac2905"

vdcStorageProfile is reffering VclObjectList when click.

But, I need to reference of vdc storage profile like this ;DynamicWrapper (Instance) : [VclVdcStorageProfile]-[class com.vmware.vmo.plugin.vcloud.model.VdcStorageProfile] -- VALUE : com.vmware.vmo.plugin.vcloud.model.VdcStorageProfile@c0e8b9d8

What is wrong ?
