Hello,
sometimes following exception is thrown (wicket 6.5.0):

That occured approximately once per month and I ignored it but today it
happened already about 10 times.
Therefore I would like to find out what the reason is.
Could someone give me a hint.
Thanks in advance

Just guessing... Maybe a page that was mounted somewhere and changed
location and a user still keeps a reference to that page?

Hi,
I have no idea.
If you find a use case where Wicket generates such broken urls then please
report it!

Hi Martin,
I checked the logs and I can confirm: the reason for all exceptions was
the url:
https://www.tierfundus.de/wicket/bookmarkable/
But I wonder how can such a url happen? I'm almost sure the user did not
modify the url in her browser manually.

Hi,
This kind of error may happen with request like
http://localhost:8080/wicket/bookmarkable/, assuming the app home page is
at http://localhost:8080/
I'll add a ticket to improve the default mappers for this case.
