Hi all,
We've been using an IRequestCycleListener in order to redirect to a certain
page for all requests if certain conditions are met. We're finding that
it's giving an exception in 1.5.4:
java.lang.IllegalStateException: Header was already written to response!

org.apache.wicket.request.handler.RenderPageRequestHandler.respond(RenderPageRequestHandler.java:167)
at
org.apache.wicket.request.cycle.RequestCycle$HandlerExecutor.respond(RequestCycle.java:781)
basically in our IRequestCycleListener we have
@Override
public void onBeginRequest(RequestCycle cycle) {
if (<condition>)) {
cycle.setResponsePage(SpecificPage.class);
}
}
Is this the wrong way to do it? Or is this behavior expected? If it's not
expected, I will file a bug for this.
Thanks,
Neil
