Konstantin Ignatyev commented on TAPESTRY-237:
----------------------------------------------
I would say there is 3rd way and it works well for me: link to logoff.jsp that
looks like this:
<%
session.invalidate();
response.sendRedirect( "app");
%>
Link:
<a href="logoff.jsp" class="menu" jwcid="logoff" >Log Off</a>
Component:
<component id="logoff" type="Any">
<binding name="href" expression="page.engine.contextPath + '/logoff.jsp'"/>
</component>
> Support for log out action
> --------------------------

> Key: TAPESTRY-237
> URL: http://issues.apache.org/jira/browse/TAPESTRY-237
> Project: Tapestry
> Type: Improvement
> Versions: 3.1
> Reporter: Vjeran Marcinko
>
> Tapestry lacks good support for quite commonly needed log out action.
> As described here :
> http://wiki.apache.org/jakarta-tapestry/FrequentlyAskedQuestions/LogoutLink
> there are currently 2 ways to achieve logging out - utilizing RestartService,
> or hacking inside Listener methods. Neither is sufficient - shortcomings of
> RestartService and ServiceLink are described, and listener method way is a
> hack utilizing some pieces of code that should normally be hidden from user.
> Let alone mentioning that later case doesn't work always - application can
> get into some strange states raising
> java.lang.IllegalStateException: Session already invalidated
> exceptions.
> It should be great if there was something easily accessible and intuitive as
> IEngine.restart() to be used for this purpose.
