Hi there,
When I'm using saveorupdate() with a class representing a table with composite keys, Hibernate always perform an UPDATE, even where an INSERT is needed

apparently, the saveOrUpdate() method check the keys to see if one of them is null ; or, in this case, none of them are null because they are representing entries from other tables

is there a way to indicate to hibernate to do an INSERT even with keys non-null with saveOrUpdate, or it is needed to manually determinate if we'll use a save() or update() call ?

thanks in advance

There are a range of options available. Hibernate will assume that an instance is an unsaved transient instance if

- the identifier property (if existant) is null.

- the version property (if existant) is null.

- you supply an unsaved-value in metadata for the class, and the value of the identifier property matched

- the <timestamp> mapping has an unsaved-value setting

- you supply a Hibernate Interceptor and return Boolean.TRUE from Interceptor.isUnsaved() after checking the instance yourself.
