Tenho uma entidade Cliente que pode ter um vendedor ou não, de qualquer maneira quando não houver vendedor o código será zero.
O que acontece é que se eu coloco cascade = CascadeType.PERSIST ele vai inserir um vendedor no cadastro, eu preciso apenas que ele salve o código do vendedor na coluna CODIGO_VENDEDOR, por outro lado se não coloco cascade = CascadeType.PERSIST ele dá a seguinte exceção:
[TopLink Warning]: 2009.12.29 04:55:36.718--UnitOfWork(31979889)--java.lang.IllegalStateException: During synchronization a new object was found through a relationship that was not marked cascade PERSIST: class horus.bean.Vendedor.

Entidade Cliente.java:
...
@ManyToOne(optional = true) //(cascade = CascadeType.PERSIST, fetch = FetchType.LAZY)
@JoinColumn(name = "CODIGO_VENDEDOR", nullable = false, updatable = true)
public Vendedor getVendedor() {
return vendedor;
}
Como resolvo isso?
