获取在标头之前使用计算设置的隐藏项目的会话状态保护违规错误 - Oracle APEX

我正在尝试使用同一页面中其他隐藏项目的值动态设置项目的标签.

我为页面中的隐藏项创建了一个计算,并将项的值设置为动态标签 - &P613_EMPLOYEE_TYPE_LABEL.

但是我收到了这个错误

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

但我已将项目的会话状态保护设置为"不受限制"

页面设置

计算

组件设置

对于隐藏项,P613_EMPLOYEE_TYPE_LABEL请将"值保护"属性设置为"否".

当Value Protected隐藏项目设置为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,校验和将不再有效,您将收到错误.
