Getting the properties of INavigationNode

Hi experts,

I'm creating an application where I have to get the INavigationNode and their propertes from the portal content. I'm able to get the all the parent nodes and their children.

For children nodes, which are pages or iviews, I'm able to get the properties by using :for e.g.

String createdBy = (String) node.getAttributeValue("com.sap.portal.pcd.unit.CreatedBy").

But for parent nodes, which are worksets, I'm getting an exception "javax.naming.directory.NoSuchAttributeException: NoSuchAttributeException is thrown from the CacheNavigationConnectorNode" for the same property.

Can you please tell how to overcome the exception or any workaround for retrieveing the properties of the parent nodes??

Thanks & Regards,
