the object complaning (i.e. 'myprodduplicate') part of composite key of jpa entity lots of fields. managed figure out problem composite key because if alter composite key utilize @embedable annotation works fine.

edit @id @manytoone @joincolumn(name="author_id") private myprodduplicate myprodduplicate; @id @column(name = "title") private string title;

the error occurs @ line (using spring info repository save db):

authorrepository.save(listitem);

is there reason above definition stop working , produce above error? spring (spring data) version upgrade cause this?

i using spring version 3.2.3.release , spring info version 1.4.2.release

java spring hibernate spring-data
