我似乎无法去上班。我正在使用冰面和一个非常简单的两列。一个具有删除等操作，另一个具有字符串（表示正则表达式）。为了让删除操作删除右行，我尝试使用以下命令将其链接到实际元素：

<html xmlns:ice="http://www.icesoft.com/icefaces/component" 
  xmlns:f="http://java.sun.com/jsf/core"
  xmlns:ui="http://java.sun.com/jsf/facelets"
  xmlns:m="http://www.mitre.org/asias/jsf">
  <ui:composition> 
    <ice:dataTable binding="#{binding}" 
      value="#{binding.editableRows}"
      var="item">
      <ice:column>
        <f:facet name="header">
          <ice:commandLink styleClass="linkBlue"
            action="#{binding.addEditableRow}">
            <ice:outputText value="Add" />
          </ice:commandLink>
        </f:facet>
        <ice:commandLink styleClass="linkBlue"
          action="#{binding.removeEditableRow}">
          <f:propertyActionListener value="#{item}" target="#{binding.actionRow}" />
          <ice:outputText value="Remove" />
        </ice:commandLink>
      </ice:column>
      <ice:column>
        <f:facet name="header">
          <ice:outputText value="Regular Expression" />
        </f:facet>
        <ice:inputText value="#{item.object}" size="100" />
      </ice:column>
    </ice:dataTable>
  </ui:composition> 
</html>

我在这方面找到的所有内容都表明我需要 JSF 1.2。我正在使用 JSF 1.2。这是我用来管理依赖项的 apache Ivy 配置文件：

<ivy-module version="2.0"

        <exclude module="jsp-api" conf="default" />
 </dependencies>
</ivy-module>

我使用 eclipse 和 IvyDE 来管理该库和选择“使用工作区元数据”运行的 Tomcat 服务器实例。是否有一些 eclipse 或 tomcat 可能会注入错误版本的 JSF？当我查看 Ivy 包含的 jsf-impl jar 时，我确实看到该 jar 中有 com.sun.faces.taglib.jsf_core.SetPropertyActionListenerImpl 和 SetPropertyActionListenerTag。我的理解是，这些应该就是所需要的了。有什么想法吗？我是不是错过了什么，或者只是疯了？

编辑：

现在我真的很沮丧。根据 BalusC 的建议，我更新了 faces-config.xml 以使用 1.2 模式定义而不是 1.1 dtd。这没有帮助。所以我四处寻找更多信息。我找到了另一篇与（这个问题）相关的stackoverflow文章，但是没有除了获取新版本的 jsf-facelets.jar（其中新/旧版本未列出）之外的解决方案。我正在使用 repo1.maven.org/maven2 上提供的最新版本（1.1.14）。所以不要在这方面进行。我的新问题是，为什么 Facelets 会与此有关？它是 JSF 核心的一部分，不是吗？我注意到在我的 jsf-impl-1.2_13.jar::META-INF/jsf_core.tld 中，有一个 setPropertyActionListener 的标签：

<tag>
    ...
    <name>setPropertyActionListener</name>
    <tag-class>com.sun.faces.taglib.jsf_core.SetPropertyActionListenerTag</tag-class>
    <body-content>empty</body-content>
    ...
</tag>

最重要的是，这可以在我的 >jsf-facelets-1.1.14.jar::com/sun/facelets/tag/jsf/core/CoreLibrary.java：

...
this.addTagHandler("setPropertyActionListener", SetPropertyActionListenerHandler.class);
...

看起来我包含的库应该足够了。知道这是怎么回事吗？我是否需要回去获得 JSF 学位才能编写简单的 Facelet？

I cant seem to get to work. I am using icefaces and a very simple with two columns. One with actions such as remove and the other with a string (representing a regular expression). In order for the remove action to remove the right row, I am trying to link it to the actual element with an :

<html xmlns:ice="http://www.icesoft.com/icefaces/component" 
  xmlns:f="http://java.sun.com/jsf/core"
  xmlns:ui="http://java.sun.com/jsf/facelets"
  xmlns:m="http://www.mitre.org/asias/jsf">
  <ui:composition> 
    <ice:dataTable binding="#{binding}" 
      value="#{binding.editableRows}"
      var="item">
      <ice:column>
        <f:facet name="header">
          <ice:commandLink styleClass="linkBlue"
            action="#{binding.addEditableRow}">
            <ice:outputText value="Add" />
          </ice:commandLink>
        </f:facet>
        <ice:commandLink styleClass="linkBlue"
          action="#{binding.removeEditableRow}">
          <f:propertyActionListener value="#{item}" target="#{binding.actionRow}" />
          <ice:outputText value="Remove" />
        </ice:commandLink>
      </ice:column>
      <ice:column>
        <f:facet name="header">
          <ice:outputText value="Regular Expression" />
        </f:facet>
        <ice:inputText value="#{item.object}" size="100" />
      </ice:column>
    </ice:dataTable>
  </ui:composition> 
</html>

Everything I have found on this says that I need JSF 1.2. I am using JSF 1.2. Here is the apache Ivy config file I am using to manage my dependencies:

<ivy-module version="2.0"

</ivy-module>

I am using eclipse with IvyDE to manage that library and a Tomcat server instance running with "Use workspace metadata" selected. Is there some eclipse or tomcat thing that might be injecting the wrong version of JSF? When I look at the jsf-impl jar that is included by Ivy, I do see that there are com.sun.faces.taglib.jsf_core.SetPropertyActionListenerImpl and SetPropertyActionListenerTag in that jar. It is my understanding that those should be all that is needed. Any Ideas? Am I missing something, or just plain going crazy?

EDIT:

Now I'm getting really frustrated. Per the suggestion from BalusC I updated my faces-config.xml to use the 1.2 schema definition instead of the 1.1 dtd. This did not help. So I search around for more information. I find another stackoverflow article pertaining to (this issue), however there was no resolution other than getting a new version of jsf-facelets.jar (of which the new/old version is not listed). I am using the latest version available on repo1.maven.org/maven2 (1.1.14). So no go on that front. My new questions are, why would facelets have anything to do with this? Its a part of the JSF core is it not? I notice that in my jsf-impl-1.2_13.jar::META-INF/jsf_core.tld, there is a tag for setPropertyActionListener:

<tag>
    ...
    <name>setPropertyActionListener</name>
    <tag-class>com.sun.faces.taglib.jsf_core.SetPropertyActionListenerTag</tag-class>
    <body-content>empty</body-content>
    ...
</tag>

On top of that, this can be found in my jsf-facelets-1.1.14.jar::com/sun/facelets/tag/jsf/core/CoreLibrary.java:

...
this.addTagHandler("setPropertyActionListener", SetPropertyActionListenerHandler.class);
...

It looks like my included libraries should be sufficient. Any idea what is going on here? Do I need to go back and get a degree in JSF to be able to write a simple facelet?

确保 faces-config.xml 的根声明按照 JSF 1.2 规范进行声明。

<faces-config version="1.2" 
    xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_1_2.xsd">

此外，数据表中的 binding="#{binding}" 看起来确实不正确，因为 #{binding} 似乎是一个托管 bean。

Ensure that the root declaration of your faces-config.xml is declared as per JSF 1.2 specification.

<faces-config version="1.2" 
    xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_1_2.xsd">

Further, the binding="#{binding}" in your datatable really doesn't look right since #{binding} seems to be a managed bean.

我真的很讨厌回答我自己的问题，尤其是因为这是一个如此简单的错误，但有时我们不得不承认并接受公开的羞辱。不管怎样，长话短说，它：

<f:setPropertyActionListener value="#{item}" target="#{binding.actionRow}" />

不

<f:propertyActionListener value="#{item}" target="#{binding.actionRow}" />

希望这会在未来帮助别人......

I really hate to answer my own question, especially since it was such a simple mistake, but sometimes we just have to fess up and accept the public humiliation. Anyway, long story short, its:

<f:setPropertyActionListener value="#{item}" target="#{binding.actionRow}" />

not

<f:propertyActionListener value="#{item}" target="#{binding.actionRow}" />

Hopefully, this will help someone else in the future...
