Wicket 1.5 mountPage with optional parameters

I am using Wicket 1.5 as web layer for application. I needed a page that could take parameter but it should be optional.

So I have an URL like this http://example.com/search/keyword/1, it has 2 parameters search (keyword) and page (1), but I want page to be optional, so that URL like example.com/search/keyword should be mapped to the same page.

I tried to map it with mountPage(“/search/${keyword}/${page}”, SearchPage.class);

But the problem was that page parameter was mandatory.

One more cool thing is that you can have optional indexed named parameters. The difference with mandatory ones is that they use hash sign instead of dollar sign – #{optional}.

A mapping like mountPage(“/mount/path/${named1}/#{named2}”, MyPage.class); will match for both requests http://host/mount/path/value1 and http://host/mount/path/value1/value2.

So I used # instead of dollar! mountPage(“/search/${keyword}/#{page}”, SearchPage.class); and it works!
