使用OmniFaces o：validateMultiple验证p：dataTable或p：treeTable中的多个输入
问题描述 投票：1回答：1
我有一个看起来像这样的UI：
游戏中不能有重复的球衣号码，所以我想要该列中所有UIInput的验证器。
我立即想到使用OmniFaces的o:validateMultiple。
但是，这似乎不起作用。通过单击按钮提交表单将导致：
22:30:20,917 SEVERE [javax.enterprise.resource.webcontainer.jsf.context] (default task-7) java.lang.IllegalArgumentException: ValidateMultiple attribute 'components' must refer existing client IDs. Client ID ':score-input-form:home-box-score-table:0:jersey-nbr-input' cannot be found.

问题：
为什么不起作用？
这是OmniFaces中的错误/缺失功能吗？
查看ValidateMultipleFields类中的OmniFaces代码
private UIInput findInputComponent(UIComponent parent, String clientId, PropertyKeys property) {
UIComponent found = parent.findComponent(clientId); <-- results in null!
if (found == null) {
throw new IllegalArgumentException(format(
ERROR_UNKNOWN_COMPONENT, getClass().getSimpleName(), property, clientId));
}
else if (!(found instanceof UIInput)) {
throw new IllegalArgumentException(format(
ERROR_INVALID_COMPONENT, getClass().getSimpleName(), property, clientId, found.getClass().getName()));
}
return (UIInput) found;
}
并查看生成的HTML ...
...我正在使用的ID似乎是正确的，并且搜索策略parent.findComponent(clientId)可能不适用于p:dataTable和p:treeTable ...🤷迭代♂等迭代组件>
如果有人可以看一下，我会很高兴。
也许对此有另一种解决方案，但我简单看不到，所以如果有另一种方法可以验证p:dataTable或p:treeTable中的多个输入，请告诉我。
编辑：
我用p:dataTable来解释我的问题，但是我不知道该组件具有完全不同的继承层次结构。 p:dataTable从UIData延伸，而p:treeTable从UITree延伸。
显然，分层数据当然更复杂。
这是我正在使用的真实用户界面：
这会导致使用o:validateUniqueColumn的异常：

<o:validateMultiple>还不是要以这种方式使用，而是以中继器组件中的单个组件为目标。它仅对XHTML源代码中定义的物理多个组件起作用，而实际上不适用于HTML输出中产生的多个组件。
