javax.el.PropertyNotFoundException：类'es.uma.informatica.sii.jsf.autenticacion.modelo.HistorialPadrinos'没有属性'nombre'

Question

我想在我的表中插入一个指向名为Usuario的实体的新记录，但是如果输入她的名字，则会发生以下错误：

查询如下：

INSERT INTO BD.HISTORIAL_PADRINOS (ID, DESCRIPCION, FECHA_APADRINAMIENTO, FECHA_CANCELACION, "NIÑO_USUARIO", USUARIO) 
    VALUES (2, 'PP', '2019-05-23', CURRENT_DATE, 'AndreaGarcia', 'JoseGarcia')

Caused by: javax.el.PropertyNotFoundException: The class 'es.uma.informatica.sii.jsf.autenticacion.modelo.HistorialPadrinos' does not have the property 'nombre'.
