As I understand it, then your second email is correct. If you don't run
the getting and updating of your components in a transaction, your Entity
gets decoupled (JPA default behavior is to decouple the Entities outside of
a transaction), so it will not save any updates done outside of the
transaction.

Hmm thinking over this again. I thought that after you persisted
something, JPA would handle it for you. So what you are saying are that if I
get a object from the persistance manager, and then update something
directly on the POJO i would then have to begin a transaction and commit it?
So just binding using a compoundmodel I would have to have a tx begin
and commit in the submit method of the form?
Like this:
public void onSubmit() {
tx.begin;
tx.commit?
}
};

my 2 cents, don't know if this is your problem:
The transaction based entity manager only commits if the update of the
data
is within a transaction. So you must wrap your update in a
transaction
(you said you used Spring, so you can configure this in your Spring
xml or
use the annotation based transactions.)
Hope this helps,

I know this is not completely related. But here goes anyway.
I have an application with several different flows. If I switch from
extended to transaction, suddenly the values in my form aren't save
to the
database(but they are saved in memory), I use spring to instantiate
entitymanager and inject. It's very strange that it does not work.
I believe that the difference between expanded and transaction based
entity manager are something todo with if it's request or session
based
right? I would actually have thought the error to show the other way
around.
Heres some code of my forms, I use the compoundpropertymodel:
add(new TextField("lifts").add(NumberValidator.POSITIVE));
add(new TextField("weight").add(NumberValidator.POSITIVE));
Button btnUpdate = new Button("updateRep", new Model("updateRep")) {
@Override
public void onSubmit() {
//make a roundtrip so JPA saves the changes
}
};
And web.xml:

<param-name>contextConfigLocation</param-name>
<param-value>classpath:zeuzContext.xml</param-value>
