-------------------------------
Summary: Mounted bookmarkable Page not recreated on Session Expiry
Key: WICKET-4997
URL: https://issues.apache.org/jira/browse/WICKET-4997
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 6.4.0
Environment: JDK 7, GlassFish 3.1.2.2
Reporter: bernard
With the default true of
org.apache.wicket.settings.IPageSettings#getRecreateMountedPagesAfterExpiry()
PageExpiryException is thrown a when any one of its links is clicked.
I find it very useful and in fact indispensible to rely on
RecreateMountedPagesAfterExpiry especially on logout links.
But it doesn't seem to work for me in 6.4.0. I think this is because
Link#getUrl() calls Component#utlFor() which requires a stateless page for this
to work:
if (page.isPageStateless())
{
handler = new
BookmarkableListenerInterfaceRequestHandler(provider, listener);
}
else
{
handler = new ListenerInterfaceRequestHandler(provider,
listener);
}
With a stateless page a url is:
http://localhost:8080/wicket/HomePage?-1.ILinkListener-toolBar-signout
With a non stateless but bookmarkable page a url is:
http://localhost:8080/wicket/page?1-1.ILinkListener-toolBar-signout
So I guess that a stateful page cannot be recovered because after session
expiry Wicket cannot find out what the page is. It is not coded in the URL.
Looking at the semantics of UrlFor(), I thought this might be a bug and I
copyed and changed the code in my Link subclass from
// if (page.isPageStateless()) {
to:
if (page.isBookmarkable()) {
It works as expected but I don't know whether it would break other things if
implemented in Wicket.
I guess I am not the only one who needs recovery for bookmarkable pages in this
way. Would it be possible to change Wicket to fix this so it becomes possible?
