为标头之前的计算设置的隐藏项获取会话状态保护冲突错误-Oracle APEX [英] getting Session state protection violation error for a hidden item that is being set with computation before header - Oracle APEX

问题描述

我正在尝试使用同一页面中其他隐藏项目的值来动态设置项目的标签.

I am trying to set the label of an item dynamically using the value of an other hidden item in the same page.

我为页面中的隐藏项目创建了一个计算，并将该项目的值设置为动态标签-& P613_EMPLOYEE_TYPE_LABEL.

I created a computation for the hidden item in the page and set the value of the item as the dynamic label - &P613_EMPLOYEE_TYPE_LABEL.

但是我收到此错误

Session state protection violation: This may be caused by manual alteration of protected page item P613_EMPLOYEE_TYPE_LABEL.

推荐答案

对于您的隐藏项目P613_EMPLOYEE_TYPE_LABEL，将值保护"属性设置为NO.

For your hidden item P613_EMPLOYEE_TYPE_LABEL set the Value Protected attribute to NO.

当隐藏项的Value Protected设置为YES时，将在加载页面时生成校验和.当您使用不同的值提交页面时，校验和不再有效，您将收到错误消息.

When Value Protected of an hidden item is set to YES a checksum is generated when your page is loaded. When you submit the page with a different value the checksum is not valid anymore and you get the error.
