What you'll want to do is to retrieve the object before closing the
PersistenceManager and storing it into request scope. That is:
PersistenceManager pm = PMF.get().getPersistenceManager();
MyUser u = pm.get // .. some retrieval code;
u.getContactInfo();
pm.close();
We'll be changing this behavio
Running into another issue. So i'm detaching my object and passing it
along in a session.
I'm now getting this error WARNING:
javax.jdo.JDODetachedFieldAccessException: You have just attempted to
access field "contactInfo" yet this field was not detached when you
detached the object. Either dont a
What state is the object in when you access its field ? (Call
JDOHelper.getObjectState(obj)).
Since no transaction boundaries or PM lifecycle is presented, it's
hard to guess. If you leave the object to become "transient" then it
will likely have its field values nulled when leaving the transaction
Right now when i set a detached copy of the object in session, it
works as intented.
req.getSession().setAttribute("account", pm.detachCopy(project));
Now do i still need to call fp.setGroup(FetchPlan.DEFAULT); or is
this repetitive?

It seems rather simple enough but i still cannot get it working
correctly. I set the annotations in my classes and modified the PM
factory
[Account]
@Persistent(mappedBy = "account", defaultFetchGroup="true")
private List projects;
[Project]
@Persistent(defaultFetchGroup="
That sounds like a good topic for a Snippets That Work blog post. I don't
have time to construct the example for you but I'd recommend reading
http://www.datanucleus.org/products/accessplatform_1_1/jdo/fetchgroup.html
If after reading this you're still not able to get your code working, please

Max,
Can you please provide an example of how to set the Account in a fetch
group? What about detaching the entire Project object and then saving
it in the session?
