Vojtěch Krása created WICKET-5371:
-------------------------------------
Summary: IllegalArgumentException: Argument 'page' may not be
null. - when sending event from asynchronous process
Key: WICKET-5371
URL: https://issues.apache.org/jira/browse/WICKET-5371
Project: Wicket
Issue Type: Bug
Components: wicket-atmosphere
Affects Versions: 6.10.0
Reporter: Vojtěch Krása
Assignee: Emond Papegaaij
I never reproduced it on local, it happens a lot on linux server behind apache
proxy(could be just coincidence). I could try to debug it, if you have no idea
why it could happen. It also seems that it happens only after server is running
for some time.
I am sending multiple events to update different panels from asynchronous
process like this:
EventBus.get(Application.get(WicketApplication.class.getName())).post(new
ComponentBuildEvent());
15:16:36 ERROR o.a.w.DefaultExceptionMapper [refreshExecutor-4]: - Unexpected
error occurred
java.lang.IllegalArgumentException: Argument 'page' may not be null.
