Question

亲爱的ADF专家，

我使用以下托管bean代码将新行插入主详细信息关系的详细信息表中。只要用户单击表中的行作为SelectionListener事件处理程序，就会使用“insertNewReturnReason”。它应该扮演createInsert绑定操作的角色，除了它尝试回滚之前创建的行，然后在主迭代器的新id（“AstAssetVOIter”）下插入一个新行。我有的另一个事件监听器是“saveAssetReturn”，它应该提交更改。

我遇到的问题是“insertNewReturnReason”，它首先进行回滚，然后在详细信息表中插入新行。由于某种原因，表单保持警告需要字段，这是另一个表中的外键。

相同的代码在另一个项目中运行正常，我没有遇到任何问题，我改变的唯一内容是迭代器的名称和视图对象。

我已将按钮的直接属性设置为true。

如果您有任何想法，请告诉我。

谢谢，

托管bean中的回滚不会忽略表单验证
