Description of problem: We have created a remote portlet (wsrp) which saves a value as session attribute: request.getPortletSession().setAttribute("inputValue", inputValue) and retrieves it again String inputValue = (String) request.getPortletSession().getAttribute("inputValue"); The problem is, that if we are placing the portlet twice one the same page, both portlets are showing the same inputValue. So the setAttribute() and getAttribute() method is not unique for the portlet instance. Version-Release number of selected component (if applicable): EPP 5.1.1 How reproducible: Always Steps to Reproduce: 1. See description Actual results: Portlet Session attributes shared accross same portlets on one page Expected results: Portlet Session attributes not shared accross same portlets on one page Additional info:
