无法更新foreignkey字段javax.el.E​​LException：value =“＃{recetteBean.recette.compte.idCompte}”：在Comptebancaire类型上写'idCompte'时出错

Question

我有两个表：CompteBancaire(idCompte,libelleCompte,montantCompte)和Recette(idRecette,libelleRecette,MantantRecette,DateRecette,idCompte) idCompte是引用Compte的外键。我有一个显示idRecette，libelleRecette，MantantRecette，DateRecette的DataTable，之后我想更新该行，以便我可以添加idCompte。但我有一个问题，idCompte没有得到更新。
