Hi everybody,

Hi James,
thanks for your help.
I think shadow models could work, when I only access non-lazy fields.
Otherwise I would get a LazyInitializationException.
Or what do you exactly mean by shadow models?

Hi everybody,
I have a little Problem with LDMs:
I have a page with a ListView and for each item in the ListView the user can
open a modalWindow to edit the item.
My Problem is, that I don't want to persist the item to the DB from the
modalWindow. Only after the User confirms the changes in the
Sorry for the delay. A shadow model basically grabs the actual model's
value in the beginning and caches it. You actually edit the shadowed model.
Then, when you're done with all of your edits you call commit on all of
your shadow models to write back into the originals. So, I don't think
Hi James,
How does this work with a Hibernate-managed object? Did you test it
with Hibernate?

It would work the same way, since it grabs its stuff up-front. Behind the
scenes, you use a LDM as the actual model.

So I guess you're not levering the optimistic locking of Hibernate.

There are many ways to skin a cat. LDMs pretty much throw optimistic
locking out the window, agreed (since they just go get a fresh copy of the
object each time typically)? So, if you want to use optimistic locking,
then you shouldn't be using LDMs in the first place.

Why?
There's nothing keeping you from storing the version too, and checking
that against the newly loaded entity... The question is... what do you
do when the version is modified from your original object?

Somehow you have to reset the cached version value (assume you'd use a
validator for this I guess), since it's not the same as the one in the db,
right?

Entity entity = ...;
if(entity.getVersion() != version) {
Session.get().warn(Someone else modified the foo in the

version = entity.getVersioni();
Using this, you have to make sure this model gets reset on form submit, too,
right? With this, you have to make sure you reset the model's cached
version value upon successful form submit, too, right?

crazy about a model implementing this functionality, especially during a
