how to order aplhabetically a selectOneMenu

[molif]

I have a h:selectOneMenu, which takes its values from a bean's properties. How can I make them display in alphabetic order?

if you are retrieving the data from a backing bean then you can use any of the standard sorting methods such as sorted sets and comperators to pre-sort your values, then add the selectItems from that pre-sorted list.

hope this helps.

Actually I take the data from the bean's properties. Like this:

<s:selectItems value="#{templateManager.template.templateFields}" var="templateField" label="#{templateField.field.parentField.code}.#{templateField.field.code}"/>

I want to order the items by templateField.field.parentField.code
I guess I have to do it in the JSF page itself? But how?

Please, help? Is there any tag or something to add to the code?

Can I user some rich faces tag instead of the seam one?

On situations like this I usually have a

List<SelectItem>

on my backing bean and that's where my

<h:selectOneMenu>

gets all its options from. On the backing I have a method that looks kinda like this (simplified and easy-to-understand version lol):

private void loadUserList()
 {
 backingBeanList = new ArrayList<SelectItem>();
 List<User> lista = new UserController().retrieveAll();

 for (User u : lista) {
 String name = u.getName();
 backingBeanList .add(new SelectItem(u, name));
 }
 }

They're automatically displayed in alphabetical order inside the selectOneMenu if I do it like this.
Hope this helps.
Cya.

Thank you for the idea, but unfortunately, it won't work. Here is my code:

public List<SelectItem> getFieldsForTemplate() {
 List<SelectItem> result = new ArrayList<SelectItem>();
 Set<TemplateField> fields = //retrieve somehow

 for (TemplateField tf : fields) {
 String label = tf.getField().getParentField().getCode() + "." + tf.getField().getCode();
 result.add(new SelectItem(tf, label));
 }
 return result;
}

In the JSP, I have:

<h:selectOneMenu id="templateFieldMenu" value="#{newTemplateField}">
 <f:selectItems value="#{templateManager.fieldsForTemplate}" />
 <s:convertEntity />
 </h:selectOneMenu>

And finally, in the application, the drop-down menu is still not ordered alphabetically. :(

Well, I created my own Comparator and it worked:

Collections.sort(result, new Comparator<SelectItem>() {
 public int compare(SelectItem sItem1, SelectItem sItem2) {
 String sItem1Label = sItem1.getLabel();
 String sItem2Label = sItem2.getLabel();

 return (sItem1Label.compareToIgnoreCase(sItem2Label));
 }
 });

Thank you however :)
