adding items into a selectOneMenu

Just add it to the array or List behind the valuebinding of f:selectItems.

Basic example:

<h:selectOneMenu value="#{myBean.selectedItem}">

<f:selectItems value="#{myBean.selectItems}" />

</h:selectOneMenu>

<h:inputText value="#{myBean.newItem}" />

<h:commandButton value="#{myBean.addNewItem}" />

MyBeanpublic void addNewItem() {

selectItems.add(new SelectItem(newItem));

}

Alright here is an Example for

<h:selectOneMenu value="#{sampleBean.selectedItem}">

<f:selectItems value="#{sampleBean.itemsList}" />

</h:selectOneMenu>

import java.util.List;

import java.util.ArrayList;

import javax.faces.model.SelectItem;

public class SampleBean{

private List<SelectItem> itemsList;

private String selectedItem;

public SampleBean(){

this.itemsList = new ArrayList<SelectItem>();

SelectItem si = new SelectItem("value1","label1");

this.itemsList.add(si);

si = new SelectItem("value2","label2");

this.itemsList.add(si);

si = new SelectItem("value3","label3");

this.itemsList.add(si);

si = new SelectItem("value4","label4");

this.itemsList.add(si);

}

public void setItemList(List<SelectItem> itemsList){

this.itemsList = itemsList;

}

public List<SelectItem> getItemList(){

return this.itemsList;

}

public void setSelectedItem(String selectedItem){

this.selectedItem = selectedItem;

}

public String getSelectedItem(){

return this.selectedItem;

}

}

Hope this might help :)

I did...It works well

my friend guess you need to get a clearity here

I'm adding 4 newly created Objects references to the List.

I'd be glad if you can try that yourself and get back :)

Hope there are no hard issues...
