How to share a simple object?
1. Get the Shared Map from the action portlet request or Jahia session.
Map map = (Map) actionRequest.getAttribute("jahiaSharedMap");
2. Put the object in the Shared Map during the portlet action phase or from a Jahia template.
map.put("date", new Date());
3. Update the Shared Map.
actionRequest.setAttribute("jahiaSharedMap", map);
