原始数据过滤器不起作用 [英] Primefaces datatable filter doesn't work
本文介绍了原始数据过滤器不起作用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
有趣的是事实是，来自Primefaces的示例代码可以工作。我的代码唯一的不同之处在于，它从数据库中收集数据，而不是在bean中生成数据。
我没有更多的线索为什么我的示例不会当我在过滤器中输入内容时，任何事情都会感谢这里的任何想法。
我的xhtml：
<！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>所有项目< / ui：define>
< ui：define name =content>
< p：dataTable var =projectvalue =＃{projectController.allProjects}widgetVar =projectTablefilteredValue =＃{projectController.filteredProjects}>
< f：facet name =header>
< p：outputPanel>
< h：outputText value =搜索所有字段：/>
< p：inputText id =globalFilteronkeyup =PF（'projectTable'）。filter（）style =width：150px/>
< / p：outputPanel>
< / f：facet>
< p：column headerText =NamefilterBy =＃{project.name}>
< h：outputText value =＃{project.name}/>
< / p：column>
< p：column headerText =Priority>
< h：outputText value =＃{project.priority}/>
< / p：column>
< p：column headerText =退出>
< h：outputText value =＃{project.exitCriteria}/>
< / p：column>
< / p：dataTable>
< / ui：define>
< / ui：composition>
我的Bean：
package com.apa.projectd.common;
import java.io.Serializable;
import java.util.List;
import javax.annotation.PostConstruct;
import javax.enterprise.context.SessionScoped;
import javax.faces.bean.ManagedBean;
import javax.inject.Inject;
import com.habony.common.Loggable;
import com.habony.projectd.ejbs.ProjectEJB;
import com.habony.projectd.enteties.Project;
@ManagedBean（name =projectController）
@SessionScoped
@Loggable
public class ProjectController implements Serializable {
private static final long serialVersionUID = 8345760187637787728L;
@Inject
private ProjectEJB projectEJB;
私人列表<项目>过滤的项目;
private List< Project>所有项目
@PostConstruct
public void loadAllProjects（）{
allProjects = projectEJB.getAllProjects（）;
}
//
// Getters和Setters
//
public List< Project> getFilteredProjects（）{
return filteredProjects;
}
public void setFilteredProjects（List< Project> filteredProjects）{
this.filteredProjects = filteredProjects;
}
public void setAllProjects（List< Project> allProjects）{
this.allProjects = allProjects;
}
public List< Project> getAllProjects（）{
return allProjects;
}
}
解决方案
p：dataTable的过滤器功能需要包装在< h：form> 标签中才能正常工作。修改的代码xhtml将：
<！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>所有项目< / ui：define>
< ui：define name =content>
< h：form>
< p：dataTable var =projectvalue =＃{projectController.allProjects}widgetVar =projectTablefilteredValue =＃{projectController.filteredProjects}>
< f：facet name =header>
< p：outputPanel>
< h：outputText value =搜索所有字段：/>
< p：inputText id =globalFilteronkeyup =PF（'projectTable'）。filter（）style =width：150px/>
< / p：outputPanel>
< / f：facet>
< p：column headerText =NamefilterBy =＃{project.name}>
< h：outputText value =＃{project.name}/>
< / p：column>
< p：column headerText =Priority>
< h：outputText value =＃{project.priority}/>
< / p：column>
< p：column headerText =退出>
< h：outputText value =＃{project.exitCriteria}/>
< / p：column>
< / p：dataTable>
< / h：form>
< / ui：define>
< / ui：composition>
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.
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.
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.
My xhtml:
<!DOCTYPE html>

}
解决方案
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>
