jsf（richfaces）只读输入文本验证 [英] jsf (richfaces) readonly input text validation

问题描述

有什么办法可以验证一个只读的jsf输入文本，但是在触发其他一些事件时值会改变吗？

Is there any way I can validate a jsf input text that is readonly but the value is changed upon some other events triggered?

推荐答案

我通过解决方法解决了这个问题。我添加了 inputHidden 字段，其中必需属性 true 它不会出现在界面上，但会被验证：

I have solved this problem with a workaround. I have added an inputHidden field that has the required attribute true that will not appear on the interface, but will be validated:

<h:inputHidden value="#{bean.value}" required="true"
                    requiredMessage="Data must be entered" />

bean.value的值被其他事件更改，而在inputHidden的某个reRender上，验证发生。

The value of bean.value is changed by other event, and at some reRender on the inputHidden, the validation takes place.
