重复视图检票口上的验证器

Question

我在重复视图（快速视图）上插入输入。当该输入有错误时（例如：RequiredValidator），提交事件将停止，但不会显示错误。如何在重复视图中验证和显示错误？

关于 QuicketView：https://github.com/vineetsemwal/quickview

Answer 1

你应该使用 https://github.com/vineetsemwal/quickview/blob/b52cc594b1118e741f38625574a38208d096419a/wicket-quickview/src/main/java/com/aplombee/ReuseAllStrategy.java 策略。

此外，您应该将 IValidator 分配给 FormComponent and/or IFormValidator 分配给 Form 组件。向项目添加验证器不会执行任何操作。

Answer 2

刚刚在 git 上推送了 master 中的更改，ReuseAllStrategy 现在不应该在重新渲染时显示陈旧数据，如果问题仍然存在或新更改破坏了其他一些东西；）在 [=14 中创建一个问题=]枢纽。打算对您之前回答的问题发表评论，但意识到您应该发表评论或投票 :)
