HI I want to populate dynamically combox items

Here is my zul file

<window id="auto_window" apply="demo.test_combo.AutoComplete"> <combobox id="combo" autodrop="true">

    </combobox>
    <label id="error" visible="false">Error Message</label>
</window>

Here is my Composer

package org2.zkoss.essentials.test_combo;

import java.util.ArrayList;

import org.zkoss.zk.ui.Component; import org.zkoss.zk.ui.event.Event; import org.zkoss.zk.ui.event.ForwardEvent; import org.zkoss.zk.ui.event.InputEvent; import org.zkoss.zk.ui.util.GenericForwardComposer; import org.zkoss.zul.Combobox; import org.zkoss.zul.Comboitem; import org.zkoss.zul.ComboitemRenderer; import org.zkoss.zul.ListModelList;

import org2.zkoss.essentials.entity.User; import org2.zkoss.essentials.entity.UserDAO;

public class AutoComplete extends GenericForwardComposer { private Combobox combo; private UserDAO userdao = new UserDAO();

@Override
public void doAfterCompose(Component comp) throws Exception {
    super.doAfterCompose(comp);
}

public void onChanging$combo(InputEvent evt) {
    System.out.println("=---------HERE_________");
    System.out.println(evt.getValue());
    for (User user : userdao.getUserList()) {
        // System.out.println(user.getFullName());
    }

    ListModelList model = new ListModelList(userdao.getUserList());
    combo.setModel(model);

    combo.setAttribute("label", "fullName");
    combo.setAttribute("value", "id");


}

public void onSelect$combo() {
    System.out.println("=---------HERE_ Select________");
    User user = (User) combo.getSelectedItem().getValue();
    System.out.println(user.getFullName());

}
