    Validate blank selectOneMenu

      Hi. I've got a selectOneMenu and I'd like to detect when the user has left it blank on form submit:

      <h:selectOneMenu id="lstRating" value="#{asset.rating}"
 required="true" requiredMessage="Rating is required.">
 <f:selectItems value="#{asset.ratingItems}" />
</h:selectOneMenu>


      The selectOneMenu gets its value from this code; note that I'm setting the first Map object element to "" the empty string, but it's not detecting it as being empty on form submit: 

      private Map<String, Object> ratingItem = null;
 private String rating;

 public Map<String, Object> getRatingItems(){
 if (ratingItem == null){
 ratingItem = new LinkedHashMap<String, Object>();
 ratingItem.put("","");
 ratingItem.put("TV-Y", "TV-Y");
 ratingItem.put("TV-Y7", "TV-Y7");
 ratingItem.put("TV-G", "TV-G");
 ratingItem.put("TV-PG", "TV-PG");
 ratingItem.put("TV-14", "TV-14");
 ratingItem.put("TV-MA", "TV-MA");
 }
 return ratingItem;
 }

 public String getRating(){
 return this.rating;
 }
 public void setRating(String rating){
 this.rating = rating;
 }

          Figured it out:

          public Map<String, Object> getRatingItems(){
 if (ratingItem == null){
 ratingItem = new LinkedHashMap<String, Object>();
 ratingItem.put("Please Select...",null);
 ratingItem.put("TV-Y", "TV-Y");
 ratingItem.put("TV-Y7", "TV-Y7");
 ratingItem.put("TV-G", "TV-G");
 ratingItem.put("TV-PG", "TV-PG");
 ratingItem.put("TV-14", "TV-14");
 ratingItem.put("TV-MA", "TV-MA");
 }
 return ratingItem;
 }


          and then also added the <rich:message> tag: 

          <h:selectOneMenu id="lstRating" value="#{asset.rating}"
 required="true" requiredMessage="Rating is required.">
 <f:selectItems value="#{asset.ratingItems}" />
 </h:selectOneMenu>
 <rich:message for="lstRating" styleClass="errors" />

            Sorry. Jumped the gun. This is the code that works:

            private ArrayList<SelectItem> ratingItems = null;

 public ArrayList<SelectItem> getRatingItems(){
 ratingItems = new ArrayList<SelectItem>();
 ratingItems.add(new SelectItem(null,"Select One..."));
 ratingItems.add(new SelectItem("TV-Y", "TV-Y"));
 ratingItems.add(new SelectItem("TV-Y7", "TV-Y7"));
 ratingItems.add(new SelectItem("TV-G", "TV-G"));
 ratingItems.add(new SelectItem("TV-PG", "TV-PG"));
 ratingItems.add(new SelectItem("TV-14", "TV-14"));
 ratingItems.add(new SelectItem("TV-MA", "TV-MA"));

 return ratingItems;
 }
