Andrii Neverov commented on WICKET-1374:
----------------------------------------
I believe the problem can be reproduced in case one overrides
WebPage(wicket.PageParameters) as protected.
Something like:
protected GroupDetailsPage(PageParameters parameters) {
super(parameters);
...
}
to solve this it's enough to change visibility of this constructor to be public.
Hope that helps.
P.S. It would be also nice if there will be some kind of message shown to the
user in this situation.
