Hi,

i want to update my entity.
When i use the Entitmanager-method create or merge, a new Entity-Id is generated, so the Column will not be updated.
Example:
Enitity Author:
I use
Entitymanager manager;
Author author;
public void setAuthor(name) //This is the Entitymodificator
manager.merge(author); or
manager.persist(author);

Thanks for any advice!
