Re: [Wicket-user] Terracotta open source and tested with wicket-examples
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.

Re: [Wicket-user] Terracotta open source and tested with wicket-examples
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)

I use Wicket 1.2.3 so Session.java:900 is
public class Session {

{
if (sessionStore == null)
{
sessionStore = getApplication().getSessionStore(); // line no
900
}
return sessionStore;
}
}
it looks like terracotta intercept assignment "sessionStore = " and add a
setter

Re: [Wicket-user] Terracotta open source and tested with wicket-examples
is the option that transient fields must be left alone (not serialized) on

Re: [Wicket-user] Terracotta open source and tested with wicket-examples
Thanks for the tips, I turn on "Honor transient" and finally my webapp
startup successfully.
after playing some pages and I switch from one server to another server.
I encounter another exception caused by transient:
WicketMessage: unable to get object, model: Model:classname=[
wicket.feedback.FeedbackMessagesModel]:attached=true, called with component
[MarkupContainer [Component id = messages, page =
ngc.wicket.pages.MainPage, path = 7:globalFeedback:feedbackul:
messages.FeedbackPanel$MessageListView, isVisible = true, isVersioned =
false]]
Root cause:
java.lang.NullPointerException

CopyOnWriteArrayList.java:152)
at wicket.feedback.FeedbackMessages.messages(FeedbackMessages.java:258)

at wicket.Page.renderPage(Page.java:368)
.
by default feedbackMessages utilize
wicket.util.concurrent.CopyOnWriteArrayList . But it internally use an
transient Object[] array_ without checking null and lazy initialization.
anyway, I may try simpler wicket application for evaluating terracotta...
It's hard to figure out what's going on for deep objects graph.

But this just seems a bug.
Can you add an issue to jira for this?
