How to retrieve the selectedItem value from <h:selectOneListBox> tag

[Anshul Chandra Saxena]

Hi

I have to develop a <h:selectOneListBox>, wherein there will be 4 items.That is the dropdown will have 4 items. I need to retrieve the value that the user is selecting. I am facing the problem while retrieving the value. Its always coming null.

My Backing Bean is:

  public class GroupCriteriaValueSettingBean {
    private javax.faces.model.SelectItem criteriaValue;
    private String selectedValue;

 
    public String getSelectedValue() {
        return this.selectedValue;
    }

   
    public void setSelectedValue(final String selectedValue) {
        this.selectedValue = selectedValue;
    }

   
    public javax.faces.model.SelectItem getCriteriaValue() {
        return this.criteriaValue;
    }

   
    public void setCriteriaValue(final javax.faces.model.SelectItem criteriaValue) {
        this.criteriaValue = criteriaValue;
    }  

The view.jsp is as:

 	<h:selectOneListbox value="#{groupCriteriaBean.selectedValue}">
    						<f:selectItem   value="#{groupCriteriaBean.criteriaValue}" itemLabel="item1" itemValue="item1" />
    						<f:selectItem value="#{groupCriteriaBean.criteriaValue}" itemLabel="item2" itemValue="item2" />
    						<f:selectItem value="#{groupCriteriaBean.criteriaValue}" itemLabel="item3" itemValue="item3" />
    						<f:selectItem value="#{groupCriteriaBean.criteriaValue}" itemLabel="item4" itemValue="item4" />
						</h:selectOneListbox>   

Now, whenever i try to get the selectedValue like

     getGroupCriteriaSettingBean().getSelectedValue();  

i get a NullPointerException.

Can anyone please help, how to retrieve the selected Value.

thanks
