Hi,

In fact, it’s hard to understand what you are trying to achieve here, but if you are looking for the id of the portlet session, you may implement the PortletListener and then via any of the requests do: request.getPortletSession().getId(). I’m not sure if it works for you, but you could give it a shot.
