I've got an annotated entity with an embedded ID having a couple of numeric fields. I'm navigating to it like x.getID().getFoo() and x.getID().getBar() but it's returning the foo and bar fields transposed. When I turn hibernate's logging level to debug, I can see they're being fetched out of the sql correctly

27 Jul 2006 15:56:47 DEBUG org.hibernate.type.IntegerType : returning '29' as column: foo4_8_0_
27 Jul 2006 15:56:47 DEBUG org.hibernate.type.LongType : returning '2' as column: bar5_8_0_

but then being garbled and transposed

27 Jul 2006 15:56:47 DEBUG org.hibernate.event.def.DefaultLoadEventListener : loading entity: [com.blah.Item#component[bar,foo]{bar=29, foo=2}]

Since all the items are attributed with their column names, there ought to be no way this can happen.

This is with hibernate3.jar 3.2.0.cr3 and hibernate-annotations.jar 3.2.0.CR1, the versions from the latest Eclipse hibernate tools.

Ok, for the record, I've tracked this down.

Quoting the annotations manual:

Quote:

Composite foreign keys (if not using the default sensitive values) are defined on associations using the @JoinColumns element, which is basically an array of @JoinColumn. It is considered a good practice to express referencedColumnNames explicitly. Otherwise, Hibernate will suppose that you use the same order of columns as in the primary key declaration.

Oops.
