Alexandru Objelean updated WICKET-2846:
---------------------------------------
Description:
Is there any particular reason why Application class wouldn't be stored in
InheritableThreadLocal instead of ThreadLocal? The problem is that I need to
be able to access Application class from a thread created when a button is
pressed. Using InheritableThreadLocal instead of ThreadLocal would solve
this problem.
Use case example:
public class MyPage extends Page {
@SpringBean
private MyService service;
//perform a polling of long running process triggered by a button click
onClickButton() {
new Thread() {
run() {
service.executeLongRunningProcess();
}
}.start();
}
}
The following example won't work well if the Application is not stored in
InheritableThreadLocal. The reason why it doesn't work, as I understand that,
is because @SpringBean lookup depends on Application instance which is not
accessible from within the thread. Having it stored inside of ITL would solve
the problem.
Thanks!
