Thanks for your answers.
I set the multi window support settings to true, and that did not make a
difference. Interestingly, the javadoc shows that multiwindow support is
true by default. I also tried setting it to false, with no luck.
However, setting the response to a new page on click seems to conserve the
original page usability. My guess is because a new page is then created, so
the current page is still valid, and the elements on it are still valid.
I am trying a bookmarkable page link instead of the onclick event, which
seems to work, except that the AJAX actions (example paging) in the original
page return an expired page message.
Still investigating, if anyone has more information it will be greatly
appreciated.
I am working in migrating an existing large JSP/Servlet/Struts app to
Wicket, and the pattern, that is open new detail windows or tabs from a AJAX
list, is heavily used by our customers. So I have to find a way to solve
this issue without limiting existing functionality. Sadly, I am pretty new
to wicket, so I dont know the internals of why a page should loses its
containers or expires in this cases.
