Hi,

I'm looking for some examples with assigned ids cascading saves and updates. I managed to work cascading saves and updates with native ids but can't make it work with assigned or composite-id.

Thanks for you help in advance,

You should add a version column to your tables with natural keys (assigned ids).

You need to do something like this since the cascade works via the save-update method. save-update uses the value of the id by default to know if it is a new item or an existing item. That's why you'll see something like unsaved-value="0" on ids.

Obviously with an assigned id, it would always look like an update, and cascading saves wouldn't work.

If you add a version column save-update can actually use that version instead of the id. There basically would be an unsaved version (possibly 0) which would be used for this determination. Add the version column and then set the unsaved-value on the version entity to the appropriate value.
