java Primefaces 4.0数据表对话框详细信息不起作用
我使用的是PrimeFaces4.0和Netbeans 6.9.1。我在这里跟随了primefaces演示:
除按钮视图外,一切正常。这是我的密码:
客户列表。xhtml
<p:growl id="msgs" showDetail="true" />
<h:form id="formTable">
<p:dataTable styleClass="table" id="customers" var="customer" value="#{customerBean.customer}">
<p:column>
<f:facet name="header">First Name</f:facet>
#{customer.firstName}
</p:column>
<p:column>
<f:facet name="header">Last Name</f:facet>
#{customer.lastName}
</p:column>
<p:column>
<f:facet name="header">Email</f:facet>
#{customer.email}
</p:column>
<p:column>
<f:facet name="header">DOB</f:facet>
#{customer.dob}
</p:column>
<p:column style="width:4%">
<p:commandButton id="selectButton" update=":formCreate" oncomplete="dialogCustomerCreate.show()" icon="ui-icon-search" title="Update">
<f:setPropertyActionListener value="#{customer}" target="#{customerBean.selectedCustomer}" />
</p:commandButton>
</p:column>
</p:dataTable>
</h:form>
<h:form id="formCreate">
<p:dialog header="Create New Customer" widgetVar="dialogCustomerCreate" resizable="false" id="dlgCustomerCreate"
showEffect="fade" hideEffect="explode" modal="true">
<h:panelGrid id="display" columns="2" cellpadding="4" style="margin:0 auto;">
<h:outputText value="First Name:" />
<h:outputText value="#{customerBean.selectedCustomer.firstName}" style="font-weight:bold"/>
<h:outputText value="Last Name:" />
<h:outputText value="#{customerBean.selectedCustomer.lastName}" style="font-weight:bold"/>
<h:outputText value="Email:" />
<h:outputText value="#{customerBean.selectedCustomer.email}" style="font-weight:bold"/>
<h:outputText value="DOB:" />
<h:outputText value="#{customerBean.selectedCustomer.dob}" style="font-weight:bold"/>
</h:panelGrid>
</p:dialog>
</h:form>
客户bean。java
public class customerBean {
private List<Customer> customer;
private Customer selectedCustomer;
/** Creates a new instance of customerBean */
public customerBean() {
customer = new ArrayList<Customer>();
}
public List<Customer> getCustomer() {
CustomersDao cust_dao = new CustomersDao();
customer = cust_dao.findAll();
return customer;
}
public Customer getSelectedCustomer() {
return selectedCustomer;
}
public void setSelectedCustomer(Customer selectedCustomer) {
this.selectedCustomer = selectedCustomer;
}
}
客户道。java
public class CustomersDao {
public List<Customer> findAll(){
List<Customer> list_cust = null;
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
String sql = "FROM Customer";
try{
session.beginTransaction();
list_cust = session.createQuery(sql).list();
session.beginTransaction().commit();
}catch(Exception e){
session.beginTransaction().rollback();
}
return list_cust;
}
}
希望有人能告诉我我的代码有什么问题。我花了两天的时间来解决它。谢谢你的阅读
# 1 楼答案
1)尝试删除
<h:form/>
,因为您没有在该对话框中提交任何信息2)尝试将
<p:commandButton update=""/>
更改为update=":display"
3)将
process="@form"
添加到你的<p:commandButton/>
4)如果那样行得通,我想你不需要这个

您的客户类别需要有一个转换器:
