我试图在主窗体和对话框中显示globalMessage。对话框中的消息仅显示第二次打开对话框的时间。
我无法让它发挥作用。有人能解决这个问题吗?我真的很感激!
我正在使用JSF Mojarra 2.2.1,Primefaces 4.0和Apache Tomcat 7.0。
这是我的观点(testView.xhtml):

这是我的bean(TestBean.java):
package de.simply.local.tbx.webbeans;
import javax.faces.application.FacesMessage;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;
import javax.faces.context.FacesContext;
@ManagedBean(name = "testBean")
@ViewScoped
public class TestBean {
public void displayMessage() {
FacesContext.getCurrentInstance().addMessage(null,
new FacesMessage(FacesMessage.SEVERITY_INFO,
"This is the summary.", "These are the details."));
}
}
