Selected element not set to the backing bean

Question

I have following field in my jsp. Selected value is not set to the element. When I did Inspect element on this drop down field in FF, it shows that element is not selected. Also its not set to the backing bean. What am I missing?

    <h:selectOnMenu id="scriptEngine"  value="#{AddScriptBean.scriptEngine}" required="true">
        <f:selectItems value="#{AddScriptBean.scriptEngines}"/>
    </h:selectOneMenu>

The backing bean code is as follows

    public List<SelectItem> getScriptEngines() {
    List<SelectItem> items = new ArrayList<SelectItem>();
    try { 
        GetScriptEngineNamesCommand command = (GetScriptEngineNamesCommand) CommandFactory.getInstance().getCommand(GetScriptEngineNamesCommand.class.getName());
        command.doExecute();
        Map<String, String> engineNames = command.getEngineNames();
        MessageSource messageSource = getMessageSource();
        Locale  locale = RequestUtils.getUserLocale((HttpServletRequest) FacesContext.getCurrentInstance()
                    .getExternalContext().getRequest(), Globals.LOCALE_KEY); 
        String label = messageSource.getFormattedMessage(locale, "com.soa.console.faces.script.select", new Object[] {});
        items.add(new SelectItem("", label));
        for (String name : engineNames.keySet()){
            items.add(new SelectItem(engineNames.get(name), name));
        }

    }catch (GException e){
        String eMessage = e.toString();
        FacesMessage msg = new FacesMessage("", eMessage);
        msg.setSeverity(FacesMessage.SEVERITY_ERROR);
        FacesContext.getCurrentInstance().addMessage(null, msg);
    }

    return items;
}

The editor offers a button for "code sample". Or just begin the line with 4 spaces. That way the editor will not try to sanitize your text. — SJuan76, May 13 '13 at 02:03
Beannames start with a lowercase letter. Also consider to keep the GETer methods from all beans slim. Try to do all the processing in some initialize method, annotated with `@PostConstruct`. — Manuel, May 13 '13 at 04:41
I am not following. Did you mean I shud do the job of adding the items in the Constructor or something? — Parag A, May 13 '13 at 05:04
You need getter setters. http://stackoverflow.com/a/2036991/892994 and also read this tutorial for better understanding http://balusc.blogspot.com/2011/09/communication-in-jsf-20.html — erencan, May 13 '13 at 06:26

I guess getter method is not calling becuase you have bounded <f:selectItems> tag to the bean with scriptEngines but your getter method is getScriptEngines().It should have been getscriptEngines().This could be the problem

May be you have some validation or conversion errors so bean values are not updating.You can use to show any messages – Archana May 14 '13 at 04:31
For a variable named as `scriptEngines`, the getter method will be `getScriptEngines()` only, hence there is no problem with the getter function name. – Logan May 14 '13 at 10:51
Some IDE will generate it as getscriptEngines().So i thought that would be the problem. – Archana May 14 '13 at 10:58
