Hi Martin, DefaultPageStore#storePage(SerializedPage page) is holding only 40 pages in cache and removes others. It seems pageSotre appending every new versions and deleting old one. Like, cache.remove(0).
I'm keeping my page in session and trying to fetch from session . But wicket looking into the PageStore not in the session. why it is not checking in session? Can I directly store a page by calling the DefaultPageStore#storePage(SerializedPage page) in a page to refresh the page version in pageStore? Ex: DefaultPageStore#storePage(this) Following code works for me, but I don't know whether this is the right solution for the issue. IDataStore dataStore=new HttpSessionDataStore(pageManagerContext,new PageNumberEvictionStrategy(500)); Any Help?
