Apache Wicket bookmarkable url added one additional parameter to the link, why?

Question

my map is

mountPage("/page/#{code}/#{name}", Page.class);

but when I click on the link

localhost/page/10/toy?2

wicket add also one parameter like a counter, when I refresh the page I have

localhost/page/10/toy?3

why?

Answer 1

This is because your page are stateful, Wicket manages its own states to your page by appending this "counter". This way, when your user navigate backward using its browser built-in functionnality, the page is displayed has it has been previously.

If you don't want such a parameter in your URL, you'll need to dig out and eradicate every stateful component in your pages.
