Weird bug
The following code:
public Object onActivate(int domainID) {
domain = (Domain)sessionManager.getSession().load(Domain.class, new Integer(domainID));
return this;
}
leads to:
HTTP ERROR: 500
Render queue error in BeginRender[core/ExceptionReport:renderobject_0]: could not initialize proxy - no Session
RequestURI=/editdomain
Powered by Jetty://
However, if I add this line:
public Object onActivate(int domainID) {
domain = (Domain)sessionManager.getSession().load(Domain.class, new Integer(domainID));
System.out.println(domain.getDomainName());
return this;
}
The error does not occur.....
My question is:
1. How do you avoid this error?
2. Why is this a Jetty error and not a Tapestry5 error message? Is this something I should report as bugreport?
Thanks!
Toby

Re: Weird bug

Looks like the ExceptionReport page failed; I suspect Tapestry was
trying to print out a value stored in the Request or Session as part
of the ExceptionReport and that failed with an exception. Thus the 500
response.

One advice: some very subtle and hard-to-find @Persist-related bugs
may happen when you return "this" in a event handler method. Return
null instead.
Another advice: Session.load() raises an exception whan the wanted
object was not loaded in this session before. As stated before, use
Session.get().
> 1. How do you avoid this error?
This is a LazyInstantiationException. It happens when you try to
lazy-load some property value from an object that is not associated
with an open session. To associate an object with a session. do
session.lock(object, LockMode.NONE).

IMHO, it is a bug.

Not quite...ideally it would at least not crash completely and manage to display a Tapestry error message....
Eager fetches are not an option for me in this case...

Hi,
this is complety unrelate to Tapestry. Go and ask the Hibernate forums
or read Hibernate docs (API of load() and get() would be a good starter).

Maybe there is a problem with lazy fetching. So if you call getXXX on
lazy attribute you force hibernate to fetch it, because it is still
managed. If you need attribute later and entity is detached getter
fails. So just call getter on attributes you need to force load and you
will be ok.

The same (if you mean the hibernate session).
With get it works instead of load...but Strange that getDomainName() which is in the same table cause it to load associated tables....

What happen when you use injected session instead of sessionmanager?
@Inject
private Session session;
public Object onActivate(int domainID) {
domain = (Domain)this.session.get(Domain.class, Integer.valueOf(domainID));
return this;
}
