Did you get this resolved? I've been working on this same problem. I haven't been able to get the HashMap to work, but using the selectItems (as mentioned above) DOES work!
I used this site as a reference:
http://jsf.iatp.org.ua/components/jsf_htmlselectmanylistbox.html
I'll post some of the code in case the link goes bad (future) and someone would still like to see it...
Static items .jsp page:
<f:view>
     <h:selectManyListbox value="#{staticPageBean.selectedItems}" size="5">
          <f:selectItem itemValue="firstName" itemLabel="First Name" />
          <f:selectItem itemValue="lastName" itemLabel="Last Name" />
          <f:selectItem itemValue="age" itemLabel="Age" />
          <f:selectItem itemValue="sex" itemLabel="Sex" />
     </h:selectManyListbox>
     <h:commandButton value="Show Selected" actionListener="#{staticPageBean.showSelected}" />
     <h:outputText binding="#{staticPageBean.selItemsOutput}" />
</f:view>
The bean for that page
public class StaticPageBean {
     //array of values of selected items
     private String[] selectedItems;
     private HtmlOutputText selItemsOutput;
     public void setSelectedItems(String[] items) {
          this.selectedItems = items;
     public String[] getSelectedItems() {
          return selectedItems;
     public void setSelItemsOutput(HtmlOutputText component) {
          selItemsOutput = component;
     public HtmlOutputText getSelItemsOutput() {
          return selItemsOutput;
     public void showSelected(ActionEvent actionEvent) {
          String str = "";
          int length = selectedItems.length;
          for(int i=0; i<length; i++) {
               str += selectedItems[ i ]+"   ";
          selItemsOutput.setValue(str);
To dynamically populate the select Items
<h:selectManyListbox value="#{dynamicPageBean.selectedItems}" size="5">
     <f:selectItems value="#{dynamicPageBean.items}" />
</h:selectManyListbox>
Code behind that
public class DynamicPageBean {
     //List of SelectItem instances
     private List items;
     public DynamicPageBean() {
          items = new ArrayList();
          SelectItem item = new SelectItem("firstName", "First Name");
          items.add(item);
          item = new SelectItem("lastName", "Last Name");
          items.add(item);
          item = new SelectItem("sex", "Sex");
          items.add(item);
          item = new SelectItem("ssn", "SSN");
          items.add(item);
     public void setItems(List items) {
          this.items = items;
     public List getItems() {
          return items;
}
