我正在使用 primefaces jsf 的数据列表。我只是从 arraylist 填充数据并显示在 datalist 中，还使用对话框进行详细视图，但是选择值对话框的问题没有显示它们。这里是代码 UI 类：
<?xml version="1.0"?>
<f:view xmlns="http://www.w3.org/1999/xhtml"
xmlns:c="http://java.sun.com/jsp/jstl/core"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:p="http://primefaces.org/ui"
xmlns:ui="http://java.sun.com/jsf/facelets">
<h:head />
<h:body>
<h:form id="form">
<p:dataList value="#{tableBean.applicantlist}" var="applicant"
id="applicants" paginator="true" rows="5"
paginatorTemplate="{PreviousPageLink} {CurrentPageReport} {NextPageLink} {RowsPerPageDropdown}"
rowsPerPageTemplate="5,10,15" type="none">
<f:facet name="header">
Applicants
</f:facet>
<h:outputText value="#{applicant.jobtitle}, #{applicant.useremail}"
style="margin-left:10px" />
<p:commandButton icon="ui-icon-search" update=":form:appDetail"
oncomplete="appDialog.show()" title="View Detail">
<f:setPropertyActionListener value="#{applicant}"
target="#{tableBean.selectedApplicant}" />
</p:commandButton>
</p:dataList>
<p:dialog header="Car Detail" widgetVar="appDialog" modal="true"
showEffect="fade">
<p:outputPanel id="appDetail" style="text-align:center;"
layout="block">
<h:panelGrid columns="2" cellpadding="5">
<h:outputLabel for="modelNo" value="Model No: " />
<h:outputText id="modelNo"
value="#{tableBean.selectedApplicant.useremail}" />
</h:panelGrid>
</p:outputPanel>
</p:dialog>
</h:form>
</h:body>
</f:view>
这是桌豆：
package com.DTO;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.bean.ViewScoped;
@ManagedBean
@SessionScoped
public class TableBean implements Serializable {
private List<InterViewDto> applicantlist;
private InterViewDto selectedApplicant;
public List<InterViewDto> getApplicantlist() {
return applicantlist;
}
public void setApplicantlist(List<InterViewDto> applicantlist) {
this.applicantlist = applicantlist;
}
public InterViewDto getSelectedApplicant() {
return selectedApplicant;
}
public void setSelectedApplicant(InterViewDto selectedApplicant) {
this.selectedApplicant = selectedApplicant;
}
public TableBean() {
getSelectedApplicant();
applicantlist = new ArrayList<InterViewDto>();
InterViewDto p1 = new InterViewDto();
p1.setJobtitle("junaid");
p1.setUseremail("email@hotmail.com");
applicantlist.add(p1);
}
}
Here is DTO Class:
package com.DTO;
import java.sql.SQLException;
import java.util.Date;
import javax.faces.application.FacesMessage;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.bean.ViewScoped;
import javax.faces.context.FacesContext;
@ManagedBean
@SessionScoped
public class InterViewDto {
String useremail,jobtitle;
Date date;
public String getUseremail() {
return useremail;
}
public InterViewDto(){
}
public void setUseremail(String useremail) {
this.useremail = useremail;
}
public String getJobtitle() {
return jobtitle;
}
public void setJobtitle(String jobtitle) {
this.jobtitle = jobtitle;
}
public Date getDate() {
return date;
}
public void setDate(Date date) {
this.date = date;
}
}
