Spring Data + Hibernate, how to update saved entity?

[Snoopman]

Hello. I'm using Spring Data and Hibernate and get an error when I'm trying to save entity with set id:

org.springframework.dao.InvalidDataAccessApiUsageException: detached entity passed to persist: com.snp.cm.persistency.contact.Contact; nested exception is org.hibernate.PersistentObjectException: detached entity passed to persist: com.snp.cm.persistency.contact.Contact
	at org.springframework.orm.hibernate3.SessionFactoryUtils.convertHibernateAccessException(SessionFactoryUtils.java:668)
	at org.springframework.orm.jpa.vendor.HibernateJpaDialect.translateExceptionIfPossible(HibernateJpaDialect.java:104)
	at org.springframework.orm.jpa.AbstractEntityManagerFactoryBean.translateExceptionIfPossible(AbstractEntityManagerFactoryBean.java:403)
	at org.springframework.dao.support.ChainedPersistenceExceptionTranslator.translateExceptionIfPossible(ChainedPersistenceExceptionTranslator.java:58)
	at org.springframework.dao.support.DataAccessUtils.translateIfNecessary(DataAccessUtils.java:213)

Please help me how can I update an entity via JpaRepositories or what config do I miss?

Can some one help me? I used OpenJpa in another project and didn't have such issue: 'save' methode did create and update. Should I implement my own update methode?
