Re: Wicket rest and retrofit rest client
Hi,
Retrofit callbacks are invoked asynchronously. Once #success() is
called, the Wicket response is probably written already.
You can't/shouldn't do anything related to Wicket in a non-request thread.

I am able to submit the form successfully.. but unable to call the
target.add(feedback);
Here is the logs :

Wicket rest and retrofit rest client
Hi all,
I am experimenting with retrofit (http://square.github.io/retrofit/) rest
client and have issue that I can't fix.
I have a form that on submit will call the wicket-rest service.
form.add(new AjaxButton("submit") {

}
@Override

error("Error creating person");
target.add(feedback);
}
});
}
});
I am able to submit the form successfully.. but unable to call the
target.add(feedback);

Re: Wicket rest and retrofit rest client
Hi,
It seems Retrofit starts a Thread ('in thread "Retrofit-Idle"') to make the
requests.
A RequestCycle is exported as a ThreadLocal only in the web container
worker threads.
See ComponentRenderer#renderPage() and WicketFilter for examples how to
construct RequestCycle.
