JPA Persistence entity with nullable composition-CodePudding

I'm trying to save - using JPA - the entity called "Proposta", and this entity has a composition with the entity "Motivo" (below my mapping)

@Entity
@Table(
    schema = "CADMAT",
    name = "TB_PROP",
    uniqueConstraints = {
        @UniqueConstraint(columnNames = {"TIPO", "COD"})
    }
)
public class Proposta implements Serializable, Identifiable {
...
@ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.MERGE, optional = true)
@JoinColumn(
        name = "COD_MOTIV",
        columnDefinition = "NUMERIC",
        referencedColumnName = "COD",
        insertable = false,
        updatable = false,
        nullable = true)
private Motivo motivo;
...
}

But when I will create a new registry this error is reported:

javax.persistence.RollbackException: java.lang.IllegalStateException: 
During synchronization a new object was found through a relationship that was not marked cascade PERSIST: 
br.gov.sp.sefaz.siafem.cm.db.model.Motivo@4ecd00b5.

I can't to put "CascadeType.PERSIST" because following my use case it's possible to save the entity "Proposta" without the entity "Motivo"

I already put the property "optional=true" and "nullable=true" in the annotations, but the error continues.

CodePudding user response：

You got the mistery Chris!!! Actually I have a constructor method in "Proposta" and it was setting properties without verifying if "Motivo" was null or not. I fixed the constructor method and it works.
