Problems with global messagens

Question

Hello,
I'm creating one page list, in this page I've created one h:messages for display global messagens. On my get property I add one message to the faces context and at first access the message isn't showed, If I trigger some action, this message will be show.
How can I show this message at first time?

I also have exactly the same problem. Even if i put something in the FacesMessage inside the constructor of the backing bean,then also nothing is displayed. It is only getting displayed if do exactly the same thing inside the actionListener method.
How do i show the message if something goes wrong inside the constructor of the backing bean?I really need to implement this feature urgently. here is a very simple protoype jsp and the corresponding backing bean.
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<h:form id="test">
     <h:messages infoStyle="font-size: 18px; font-weight: bold; color: #000066"
                                       errorStyle="font-size: 20px; font-weight: bold; color:#FF0000"/>
    <h:inputText value="#{testBean.simpleprop}"/>
    <h:commandButton actionListener="#{testBean.submit}"/>
</h:form>Here is the backingBean:
public class TestBean {
    public TestBean() {
        FacesContext.getCurrentInstance().addMessage(null,new FacesMessage(FacesMessage.SEVERITY_ERROR,"somemessage","dgfdhfd"));
    private String simpleprop;
      public String getSimpleprop() {
        return simpleprop;
    public void setSimpleprop(String simpleprop) {
        this.simpleprop = simpleprop;
       public void submit(ActionEvent e){
        System.out.println("jcckch");
        FacesContext.getCurrentInstance().addMessage(null,new FacesMessage(FacesMessage.SEVERITY_ERROR,"chbchbcb","ahnagagafgs"));
}
