Did you try putting the Cascade persist and cascade merge on the
item->header relation? I think the exception means that the item is

I need transactions in my webapp using the OpenSessionInView filter pattern to
enable use of entities in my JSPs.
I am not using an EJB3 container, and I am restricting my use of Spring, or at
least trying to, to the IoC and transaction manager (for XML transaction
configuration).
Is there a

I'm interested in this as well, I'm trying to build a Struts2 app to
be distributed that provides a "best-practices" example of JPA in
struts2 (a refactoring of the struts-mailreader for those who are
familiar with it). I want to keep Spring out, so I was thinking of
adapting the OpenSession
So I'm not the only one then.
I just hit another issue at the data access layer/DAOs. According to the OpenJPA
docs, the idiomatic design for the data access layer is to use an injectable
Entity Manager Factory which provides a fresh Entity Manager each time.

Can you suggest me how to set permanently all result lists to be writable by
default?

There are a few different concepts at play here. One is the

For the benefit of the list (since I've had e-mails asking if I solved
it), the workaround I used was to copy the list using new
ArrayList(openjpaList) and called subList on that.
