Retrieve selected values from dynamically generated HtmlSelectManyListBox

[tamir mahmood]

Hi ,

I am new to JSF , i am facing a problem , it is like this . My page is dynamically generated , as there is no prior set/get methods . To get the user input I am using a Map in my backing bean , and i am binding each element in the page using valueBinding give some key dynamically . This works fine with text box my actionListener is getting called and I am able to print the input , but when I tried to retrieve the selected values of HtmlSelectManyListBox , my ActionListener is not getting called.The code is as follows ,

    public HtmlPanelGrid getFormElements() {
  Application app = FacesContext.getCurrentInstance().getApplication();
    grid = new HtmlPanelGrid();
    List children = grid.getChildren();
 
    HtmlOutputText t1 = new HtmlOutputText();
    t1.setValue("I am trying too hard , please work");
    children.add(t1);
 
    HtmlPanelGroup group = new HtmlPanelGroup();
    List c = group.getChildren();
    
    
    HtmlInputText input = new HtmlInputText();
    input.setId("a1");
    input.setValue("Tamir");    
    String bind = "#{user.datafield['a1']}";
    input.setValueBinding("value",app.createValueBinding(bind));
    c.add(input);
    String bind1 = "#{user.datafield['a2']}";
    List valueList = new ArrayList();
    HtmlSelectManyListbox selectManyBox = new HtmlSelectManyListbox();
    selectManyBox.setId("listbox");
    selectManyBox.setValue(new String[]{"Domain A", "Domain B"});    
    selectManyBox.setValueBinding("value",app.createValueBinding(bind1));
    
    UISelectItems items = new UISelectItems();
    SelectItem selectCheckItems = new SelectItem("Domain A","Domain A");
    valueList.add(selectCheckItems);
 selectCheckItems = new SelectItem("Domain B","Domain B");
 valueList.add(selectCheckItems);
 selectCheckItems = new SelectItem("Domain C","Domain C");
 valueList.add(selectCheckItems);
 selectCheckItems = new SelectItem("Domain D","Domain D");
 valueList.add(selectCheckItems);
 items.setValue(valueList);
 selectManyBox.getChildren().add(items);
 c.add(selectManyBox);
    
    
 
 
    children.add(group);
 
    return grid;
 
  }

ActionListener is as follows

public void setData(ActionEvent evt){
  System.out.println("Inside Set Data method");  
  System.out.println((String)datafieldMap.get("a1"));
  
  String[] selectChoices=(String[])datafieldMap.get("a2");
  if(selectChoices != null & selectChoices.length > 0){
  for(int i=0;i < selectChoices.length;i++){
  System.out.println(selectChoices[i]);
  }
  }
  
  }
 
  

My page has the following code

<h:form id="form1">
 <h3>
 Welcome to JavaServer Faces,
 <h :-o	 utputText value="#{user.name}"/>!
 </h3>
<h :-P	 anelGrid  binding="#{user.formElements}">
 </h :-P	 anelGrid>
 
<p>
<h:commandButton value="Submit" actionListener="#{user.setData}"/>
</p>
</h:form>
 
  

Request your guidance , Thanks in Advance
