(There is a test case..second line of comment!)

However, maybe it is my mistake,

could be that I need a 'PrimaryKey class',
(http://www.datanucleus.org/products/accessplatform_3_3/jdo/primary_key.html)

I will check

No PK class defined (required by the JDO spec), and the DN helper to auto-generate a PK (PrimaryKeyGenerator) is only applicable for persistable fields (not persistable properties). So either use persistable fields, or provide a PK class, or contribute code to make the PrimaryKeyGenerator support persistable properties
