How can I pre-define the default selection in a SelectOneChoice?

Question

How can I pre-define the default selection in a SelectOneChoice?
(1) Here's my JSF-code:
<af:selectOneChoice label="#{res['usercreate.input.sex']}"
value="#{bindings.Sex.inputValue}"
binding="#{SelectListBean.sexlist}"
readOnly="false" autoSubmit="false">
<af:selectItem label="#{res['data.sex.women']}" value="1"/>
<af:selectItem label="#{res['data.sex.man']}" value="2"/>
</af:selectOneChoice>
(2): manged bean: to set the default value to be the first in the list, my managed bean as follows:
import oracle.adf.view.faces.component.core.input.CoreSelectOneChoice;
public class MBSListBean {
private CoreSelectOneChoice sexlist;
public MBSListBean() {
public void setSexlist(CoreSelectOneChoice sexlist) {
this.sexlist = sexlist;
this.sexlist.setValue(1);
public CoreSelectOneChoice getSexlist() {
return sexlist;
(3) when i launch the page, it often gives me such warnings:
WARNUNG: Could not find selected item matching value "1" in CoreSelectOneChoice[UIXEditableFacesBeanImpl, id=_id7]
how to solve the problem ?
Thanks,

You could also set the default on your entity or viewobject, in the properties of your attribute.
