Table and session problem
Hi,
I'm having a problem with the contrib:Table component and sessions. My
source for the table is this:
public Collection getDataSource(){
return ((Visit)getVisit()).getResultList();
}
The visit object result list is populated in another page. All works
fine except when I return to the page after a session time out. I don't
get forwarded to the session time out page (which is what I want) but
instead get an empty table displayed (I guess because a new visit
object is being created in the new session, and the result list is of
course empty).
Anyone any ideas how to get round this,
thanks in advance,
Jonny

Thanks for the reply.
I'm using PageLink to return to the page. It looks like I need to
implement a stateful PageLink.
I tryed your second suggestion earlier this afternoon. When I throw a
StaleSessionException myself I do not get forwarded to
StaleSession.page, but Exception.page instead.

How are you returning to the page?
You can specify that DirectLink/ActionLink's are stateful, which should
take care of this situation for you if it is a hyperlink coming to the
offending page.
Also, you can also call IEngine.isStateful() and throw
StaleLinkException yourself if you like.
I haven't tried what I've said here, but seems that these should do the
trick.

Re: Table and session problem
Posted by Jonny Wray <jo...@yahoo.com>.
Thanks, I see the difference between engine.getVisit() and getVisit()
now. But, this still does not solve my problem, I just get a null visit
object rather than an empty one.
Basically, if I return to a page after the session has timed out
shouldn't the EngineService detect this, throw a StaleSessionException
and the framework be forwarded to StaleSession.page? This is what I
want to happen, but on this page that uses the visit object I get
either a new, empty visit object (if I call getVisit) or a null visit
object (if I call engine.getVisit()).
Any ideas what I'm missing here, or how to fix this?
thanks,
Jonny

engine.getVisit() returns null if session is timed out. I don't know
where are you checking for time-out, but you should use
getEngine().getVisit() instead of just getVisit(). Hope that helps...
