Primefaces 数据表过滤器不起作用 [英] Primefaces datatable filter doesn't work
问题描述
我必须做一些根本错误的事情，我使用数据表将代码精简到最低限度，并启用了一个列过滤器和一个全局过滤器.
I must do something fundamentally wrong, I stripped down the code to the bare minimum with a data table and enabling one column filter and a globe filter.
有趣的是来自 Primefaces 的示例代码有效.与我的代码的唯一区别应该是它从数据库收集数据，而不是在 bean 中生成数据.
The funny thing is that the example code from Primefaces works. The only difference to my code should be that it gathers data from a DB rather than generating it in the bean.
当我在过滤器中输入某些内容时，我不知道为什么我的示例没有执行任何操作，如果您有任何想法，我将不胜感激.
I have no more clues why my example doesn't do anything when I type something in the filter would be appreciate any ideas here.

}
}
推荐答案
p:dataTable 的过滤器特性需要包含在
The filters features of p:dataTable need to be wrapped in <h:form> tags for work fine. The code xhtml modified would:
<!DOCTYPE html>
<html xmlns="http://www.w3c.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:p="http://primefaces.org/ui">
<ui:composition template="layout.xhtml">
<ui:define name="title">All Projects</ui:define>
<ui:define name="content">
<h:form>
<p:dataTable var="project" value="#{projectController.allProjects}" widgetVar="projectTable" filteredValue="#{projectController.filteredProjects}">
<f:facet name="header">
<p:outputPanel>
<h:outputText value="Search all fields:" />
<p:inputText id="globalFilter" onkeyup="PF('projectTable').filter()" style="width:150px" />
</p:outputPanel>
</f:facet>
<p:column headerText="Name" filterBy="#{project.name}">
<h:outputText value="#{project.name}" />
</p:column>
<p:column headerText="Priority">
<h:outputText value="#{project.priority}" />
</p:column>
<p:column headerText="Exit">
<h:outputText value="#{project.exitCriteria}" />
</p:column>
</p:dataTable>
</h:form>
</ui:define>
</ui:composition>
