hhmm.... as Wicket always check serializable, I think my app's session does
not refererence to non-serializable WebApplication. but the stack trace
shows:
com.tc.object.ClientObjectManagerImpl.lookupOrCreate(ClientObjectManagerImpl.java:306)
com.tc.object.tx.ClientTransactionManagerImpl.fieldChanged(ClientTransactionManagerImpl.java:507)
com.tc.object.TCObjectImpl.objectFieldChanged(TCObjectImpl.java:272)
wicket.Session.__tc_setsessionStore(Session.java)
wicket.Session.getSessionStore(Session.java:900)
wicket.Session.getAttributeNames(Session.java:881)
wicket.Session.visitPageMaps(Session.java:753)
wicket.Session.init(Session.java:581)
wicket.RequestCycle.prepare(RequestCycle.java:911)
wicket.RequestCycle.step(RequestCycle.java:986)
wicket.RequestCycle.steps(RequestCycle.java:1084)
wicket.RequestCycle.request(RequestCycle.java:454)
wicket.protocol.http.WicketServlet.doGet(WicketServlet.java:219)
javax.servlet.http.HttpServlet.service(HttpServlet.java:689)
I use Wicket 1.2.3 so Session.java:900 is
public class Session {
protected ISessionStore getSessionStore()
{
if (sessionStore == null)
{
sessionStore = getApplication().getSessionStore(); // line no
900
}
return sessionStore;
}
}
it looks like terracotta intercept assignment "sessionStore = " and add a
setter
wicket.Session.__tc_setsessionStore(Session.java)
but sessionStore referenced by Application....

Why would you put a reference to the application in your session
anyway? You can get the current app like Application.get(). Otherwise,
you can make the field transient, though when it gets deserialized,
you'd have to set the field yourself somehow.
