无法使PrimeFaces RequestContext.getCurrentInstance().openDialog()工作 [英] Can't get PrimeFaces RequestContext.getCurrentInstance().openDialog() to work
问题描述
无法使PrimeFaces RequestContext.getCurrentInstance().openDialog()正常工作.我将示例代码从primefaces展示柜中取出，但没有打开对话框.我正在使用在Wildfly 8.2.0.Final上运行的PF 5.1.有什么想法吗?
Can't get PrimeFaces RequestContext.getCurrentInstance().openDialog() to work. I lifted the example code right out of the primefaces showcase, but I never get a dialog to open up. I'm using PF 5.1 running on Wildfly 8.2.0.Final. Any ideas what's up?
DFView.java
DFView.java
@ManagedBean(name = "dfView")
public class DFView {
public void chooseCar() {
RequestContext.getCurrentInstance().openDialog("selectCar");
}
public void onCarChosen(SelectEvent event) {
Car car = (Car) event.getObject();
FacesMessage message = new FacesMessage(FacesMessage.SEVERITY_INFO, "Car Selected", "Id:" + car.getId());
FacesContext.getCurrentInstance().addMessage(null, message);
}
}
和我的dialogplay.xhtml
and my dialogplay.xhtml
<!DOCTYPE html>
<ui:composition xmlns="http://www.w3.org/1999/xhtml" template="/WEB-INF/templates/template.xhtml"
xmlns:ui="http://xmlns.jcp.org/jsf/facelets" xmlns:h="http://xmlns.jcp.org/jsf/html"
xmlns:p="http://primefaces.org/ui">
<ui:define name="body">
<h:form>
<p:growl id="growl" showDetail="true" />
<p:commandButton value="Select Car" icon="ui-icon-extlink" actionListener="#{dfView.chooseCar}">
<p:ajax event="dialogReturn" listener="#{dfView.onCarChosen}" update="growl" />
</p:commandButton>
</h:form>
</ui:define>
</ui:composition>
推荐答案
请在您的faces-config中检查"selectCar"是否为有效的导航规则，该规则引用了dialogplay.xhtml. (或使用wittakarn的解决方案，这更容易)
Please check "selectCar" is a valid Navigation Rule in your faces-config which references dialogplay.xhtml. (or use wittakarn's solution, which is easier)
如果是这种情况，请检查您的faces-config是否包含Dialog Framework配置(Primefaces 5.1用户指南中的第519页，很容易错过):
If that is the Case, check that your faces-config contains the Dialog Framework Configuration (Page 519 in the Primefaces 5.1 Users Guid, it's easy to miss):
<application>
<action-listener>
org.primefaces.application.DialogActionListener
</action-listener>
<navigation-handler>
org.primefaces.application.DialogNavigationHandler
</navigation-handler>
<view-handler>
org.primefaces.application.DialogViewHandler
</view-handler>
</application>
