Unknown integral data type for ids : java.lang.String while creating DBRE

[mkandrat]

Hi,

I am using Spring Roo 1.2.2 Release version. Created domain class using DBRE. Getting below exception when try to save data.

org.springframework.orm.jpa.JpaSystemException: org.hibernate.id.IdentifierGenerationException: Unknown integral data type for ids : java.lang.String; nested exception is javax.persistence.PersistenceException: org.hibernate.id.IdentifierGenerationException: Unknown integral data type for ids : java.lang.String

As per the Bug https://jira.springsource.org/browse/ROO-1040, i have commented // @GeneratedValue(strategy = GenerationType.AUTO) and added below code in Domain class.

@PrePersist
public void generateAreaKey() {
setAreaKey(java.util.UUID.randomUUID().toString()) ;
}


But the data is not persisted into DB. Seems that this workaround is not perfect one. Please let me know how to resolve the issue.

Thanks,
