Hi,
i'm a bit confused about what you want to do.
Lets clear up by consructing an example:
If i understand you correct you want your application to provide a
component (UISelectMany) which is rendered as a listbox
(<select size=5 ...> <option ... >label</option>+ </select>).
The items should created by application and put into the component.
The Bean class:
===============================================================================
package org.apache.myfaces.examples;
import javax.faces.component.UISelectMany;
import javax.faces.component.UISelectItems;
import javax.faces.model.SelectItem;
import java.util.List;
import java.util.ArrayList;
public class TestBean {
private UISelectMany selectMany;
private Object[] selectedItems;
public TestBean() {
selectMany = new UISelectMany();
selectMany.setId("selectMany");
UISelectItems items = new UISelectItems();
items.setId("selectManyItems");
items.setValue(createSelectItems());
selectMany.getChildren().add(items);
}
private Object createSelectItems() {
List items = new ArrayList();
for (int i = 0; i < 10; i++){
items.add(new SelectItem("item" + i, "Item No. " + i));
}
return items;
}
public UISelectMany getSelectMany() {
return selectMany;
}
public void setSelectMany(UISelectMany selectMany) {
this.selectMany = selectMany;
}
public Object[] getSelectedItems() {
return selectedItems;
}
public void setSelectedItems(Object[] selectedItems) {
this.selectedItems = selectedItems;
}
}
===============================================================================
and the jsp page:
===============================================================================
<%@ page import="org.apache.myfaces.examples.TestBean"%>
<%@ taglib uri="http://java.sun.com/jsf/html"; prefix="h"%>
<%@ taglib uri="http://java.sun.com/jsf/core"; prefix="f"%>
<%
Object testbean = pageContext.getAttribute(
"TestBean", PageContext.SESSION_SCOPE);
if (testbean == null) {
pageContext.setAttribute(
"TestBean", new TestBean(), PageContext.SESSION_SCOPE);
}
%>
<html>
<body>
<f:view>
<h:form>
<h:selectManyListbox id="selectMany"
binding="#{TestBean.selectMany}"
value="#{TestBean.selectedItems}" />
<h:commandButton value="Submit"/>
</h:form>
</f:view>
</body>
</html>
===============================================================================
If this is what you want to do, it should be easy to adapt it to your needs.
If not you shoud explain a bit clearer what you want.
