我似乎无法开始工作。我正在使用icefaces和一个非常简单的两列。一个具有删除等操作,另一个带有字符串(表示正则表达式)。为了使删除操作删除右行,我尝试使用:
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>
我在此发现的一切都说我需要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:

我正在使用evy与IvyDE来管理该库以及运行&#34;使用工作空间元数据&#34;的Tomcat服务器实例。选择。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,那些应该是所有需要的。有任何想法吗?我错过了什么,或者只是发疯了?
修改
现在我变得非常沮丧。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。这没有用。所以我四处寻找更多信息。我找到了另一个与(this issue)有关的stackoverflow文章,但是除了获得新版本的jsf-facelets.jar(其中没有列出新版本/旧版本)之外,没有解决方案。我使用的是repo1.maven.org/maven2( 1.1.14)上提供的最新版本。所以不要去那个方面。我的新问题是,为什么facelets与此有关?它不是JSF核心的一部分吗?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 中找到:
...
this.addTagHandler("setPropertyActionListener", SetPropertyActionListenerHandler.class);
...
看起来我所包含的库应该足够了。知道这里发生了什么吗?我是否需要返回并获得JSF学位才能编写一个简单的facelet?
答案 0 :(得分:1)
确保根据JSF 1.2规范声明faces-config.xml
的根声明。
<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}"
确实看起来不正确,因为#{binding}
似乎是一个托管bean。

我真的很讨厌回答我自己的问题,特别是因为这是一个如此简单的错误,但有时我们不得不接受公众的羞辱。无论如何,长话短说,它的:
<f:setPropertyActionListener value="#{item}" target="#{binding.actionRow}" />
不
<f:propertyActionListener value="#{item}" target="#{binding.actionRow}" />
希望这将有助于其他人......
