I think you've misunderstood where problem is.
I don't have a problem with persisting items, I have a problem with
changing item and getting my changes back.
Problem is in this code.
public void changeItems(Key containerKey, Key itemKey) {
// START TRANSACTION
Container container = jpaTemplate.find(Container.class,
containerKey);
Item changedItem = jpaTemplate.find(Item.class, itemKey);
changedItem.setValue("xxx"); // <------ CHANGE ITEM VALUE
jpaTemplate.flush();
logger.fatal("changed item: " + changedItem);
for (Item item : container.getItems()) {
// Query returns items and one of the items has beed
changed above
logger.fatal("list item: " + item); // <------ ITEM
DOES NOT CONTAIN CHANGES MADE ABOVE
}
// COMMIT TRANSACTION
}
