h:inputText, h:selectOneMenu 在重新渲染后显示旧值
我在表的每一行都有 h:inputText, h:selectOneMenu 。我在每行的末尾还有删除按钮。单击删除按钮相应行被删除。当我删除一行时，表中显示的行数减少一，但数据仍然显示旧行。考虑以下示例：
考虑我有三行：
Text1 comexBox1 delete1
Text2 组合框2 删除2
Text3comboxBox3delete3
单击delete1：
当前行为
Text1 组合框1 删除2
Text3comboxBox3delete3
预期行为
Text2 组合框2 删除2
Text3comboxBox3delete3
我观察到的一件奇怪的事情是，当我将inputText更改为outputText时，数据正在刷新。我仅在使用输入组件（textArea、testBox、组合框和复选框）时遇到此问题。
我在门户环境中使用JSF1.2、Spring web-flow。
I have h:inputText, h:selectOneMenu in every row in a table. I also have delete button at the end of each row. On-click of delete button corresponding row is deleted. When I delete a row, number of rows displayed in the table is reduced by one but the data is still displayed from old row. Condider the following example:
Consider I have three rows:
Text1 comboxBox1 delete1
Text2 comboxBox2 delete2
Text3 comboxBox3 delete3
on-click of delete1:
Current behaviour
Text1 comboxBox1 delete2
Text3 comboxBox3 delete3
Expected behaviour
Text2 comboxBox2 delete2
Text3 comboxBox3 delete3
One weird thing that I observed is that, when I changed inputText to outputText the data is getting refreshed. I am facing this problem only with input components (textArea, testBox, combo-box and check-box).
I am using JSF1.2, Spring web-flow in portal environment.

因此，仅显示输入组件的提交值，而不显示模型值。这表明特定组件上的验证失败。您究竟如何调用删除按钮？我的印象是您正在抑制验证错误并删除非操作方法内的行。
这不是删除数据表行的正确方法。您所需要的只是删除按钮上的
immediate="true"（并确保同一行的输入组件上没有此属性！）。So, only the submitted value of the input component is been shown instead of the model value. This suggests that validation has failed on the particular component. How exactly are you invoking the delete button? I have the impression that you're suppressing validation errors and removing the row inside a non-action method.
This is not the proper way of deleting a datatable's row. All you need is an
immediate="true"on the delete button (and ensure that you don't have this attribute on the input components of the same row!).
