JSF1.2：ui:repeat、a4j:repeat 和 t:datalist 标签之间的区别
您知道主题中提到的标签有什么区别吗？
我认为它们应该产生几乎相同的结果，但事实证明，在某些情况下，ui:repeat（facelets 标签）无法按您的预期工作，尽管它也被视为基本迭代组件。
t 代表 tomahawk，a4j 是 richfaces 前缀。
欢迎任何评论。
Do you know what is the difference between the tags mentioned in the subject?
I thought they should produce pretty much the same result but it turned out that in some cases ui:repeat (a facelets tag) is not working as you would expect, although it's also considered a basic iteration component.
t is for tomahawk and a4j is a richfaces prefix.
Any comment is welcome.

ui:repeat在某些情况下确实存在错误。至于与其他两个的区别，归结为它不是UIData组件，而其他两个是。Ajax4jsf

UIRepeat确实不扩展UIData。UIData提供的可继承代码库相当成熟（尽管它并不总是像应有的那样高效）。 Facelets 的UIRepeat仍需要进一步完善。ui:repeat无法扩展UIData，因为它是 Facelets（视图技术）的一部分，而不是 JSF（基于组件的 MVC 框架）的一部分。它最初也是由另一个团队开发的。由于尚不清楚您到底在谈论什么问题，因此很难判断它是否实际上是已知的错误之一，或者只是一种误解/滥用。至少，此处概述了与

UIRepeatdoes not extendUIData.The inheritable codebase provided by
UIDatais pretty mature (although it is not always as efficient as it ought to be). The Facelets'UIRepeatstill needs to be polished more. Theui:repeatcan't extendUIData, because it's part of Facelets, the view technology, not of JSF, the component based MVC framework. It was also initially developed by a different team.Since it's unclear what issue exactly you're talking about, it's hard to tell whether it's actually one of its known bugs or just a misinterpretation/abuse. At least, here is an overview of all known bugs related to
ui:repeat.
