I'm using Guice component injection with Wicket and it works grreat:
MyPanel {
@Inject
private MyService myService;
MyPanel(String id) {
super(id);
myService.doSomething();
}
//...
}
HOWEVER, now I'm tryin' to send my service to a thread that I create, like
so:
MyPanel {
@Inject
private MyService myService;
MyPanel(String id) {
super(id);
myService.doSomething();
}
void onEvent() {
Thread t = new MyThread(myService) {
// ...uses passed-in myService in run() method
}
}
}
BUT of course Guice is proxying my service and it doesn't expect it in a
non-Wicket thread. At runtime I get:
org.apache.wicket.WicketRuntimeException: There is no application attached
to current thread pool-1-thread-1

This makes sense to me why this is happening (Guice/Wicket need a Wicket
context to deserialize the instance).
SO, I guess this means I have to pull-and-set those services on the thread
myself...unless there is a better way?
