Hi, I have the same problem, but my page is a non-bookmarkable page which has only one constructor : public MyPage(Page backpage, Model<T> model).
I don't see how setResponsePage can solve the problem for me unless I create a default constructor. I'm reluctant to do so because the page is some sort of a "edit" page in which the user can edit the passed model object and I don't want this page to be accessible in anyway but through a link that creates this specific page for a specific model. Any help will be greatly appreciated!
