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.tx.ClientTransactionManagerImpl.fieldChanged(ClientTransactionManagerImpl.java:507)

I use Wicket 1.2.3 so Session.java:900 is

sessionStore = getApplication().getSessionStore(); // line no

it looks like terracotta intercept assignment sessionStore = and add a
setter

Hi all,
Sorry to spam you with this, but you might be interested in this
announcement

We successfully tested wicket-examples (with the help of some people

indeed - certainly now that it is open sourced!
Anyway, just FYI, and I'd be interested to learn the experiences of
others.

is the option that transient fields must be left alone (not serialized) on

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

by default feedbackMessages utilize

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.
