AbstractHttpSessionStore.bind throws null pointer exception
-----------------------------------------------------------
Key: WICKET-3120
URL: https://issues.apache.org/jira/browse/WICKET-3120
Project: Wicket
Issue Type: Bug
Reporter: EC
Fix For: 1.4.12
The method gets a n HttpSession, but does not check for null before it uses it.
HttpSession httpSession = getHttpSession(webRequest);
// register an unbinding listener for cleaning up
String applicationKey = application.getApplicationKey();
httpSession.setAttribute("Wicket:SessionUnbindingListener-" +
applicationKey,
... ...
The method getHttpSession is allowed to return null and most other places in
the code check for null before using the session.
