ActionEvent triggered from CommandButton not updating GUI

Question

Hi,
I’ve a commandbutton an actionListener as show, and had hoped that pressing this button would display updated values for the outputText component
<h:commandButton actionListener="#{dashBoardBean.displayLastWeek}" value="Last Week"  styleClass="logbt" />
<h:outputText value="#{dashBoardBean.chartType}" />Associated methods from DashBoardBean
import javax.faces.event.ActionEvent;
private String chartType = "thisWeek";
     * @return the chartType
    public String getChartType() {
        return chartType;
     * @param chartType the chartType to set
    public void setChartType(String chartType) {
        this.chartType = chartType;
    public void displayLastWeek(ActionEvent ae) {
        chartType = "lastWeek";
    }However the output is not being updates and pressing the button has no effect..... Hopefully someone can point out what I am doing wrong
Thanks....

Do you have <h:messages/> on your page?
Have you tried to verify if the action listener method is actually called?
What is the scope of your bean?
Have you tried the smallest possible example to reproduce the problem?
