This way of obtaining a Session I think is not a good idiom. May be there are things that happens behind the scene when obtaining a session, that's probably why you are not getting a NPE the first time you call getSession(false) in your code...because "something" already created it.
S2 have a Map abstraction of session: http://struts.apache.org/2.1.8.1/docs/how-do-we-get-access-to-the-session.html HTH 2010/1/14 Cimballi <cimballi.cimba...@gmail.com>: > Hi, > > I have a problem with a JSP and the session the first time I call the > action which redirects to the page. > The action sets a variable in the session using the code : > final HttpSession session = > ServletActionContext.getRequest().getSession(false); > session.setAttribute(name, value); > > Then, the action redirects to a page where there is a select tag like : > <s:select name="xxx" list="#session.sessionValue" /> > > If I start the application, the first time I call the page I have the > following error : > org.apache.jasper.JasperException: tag 'select', field 'list', name > 'xxx': The requested list key '#session.sessionValue' could not be > resolved as a collection/array/map/enumeration/iterator type.
