<s:selectItems> problem
Hi,
I've got problem with <s:selectItems> control. I try to populate it with the list from my Dictionary class:
@Name("dictionary")
public class Dictionary implements Serializable{
List<SelectItem> sexList;
public Dictionary(){
sexList = new ArrayList<SelectItem>();
sexList.add(new SelectItem('F', ResourceBundle.instance().getString("sexFemale")));
sexList.add(new SelectItem('M', ResourceBundle.instance().getString("sexMale")));
employedList = new ArrayList<SelectItem>();
employedList.add(new SelectItem("0", ResourceBundle.instance().getString("labelYes")) );
employedList.add(new SelectItem("1", ResourceBundle.instance().getString("labelNo")) );
}
public Dictionary createInstance(){
Dictionary dictionary = new Dictionary();
return dictionary;
}
public List<SelectItem> getSexList() {
return sexList;
}
public void setSexList(List<SelectItem> sexList) {
this.sexList = sexList;
}
}
my facelet contains the following code:
...
<h:selectOneMenu value="#{profileHome.instance.sexFlag}">
<s:selectItems value="#{dictionary.sexList}" var="sex" label="#{sex.label}" />
</h:selectOneMenu>
...
When the page is rendered I get the error:

And when I use <f:selectItems>:
...
<h:selectOneMenu value="#{profileHome.instance.sexFlag}" >
<f:selectItems value="#{dictionary.sexList}"/>
</h:selectOneMenu>
...
the page is rendered correctly.
I don't know what I am doing wrong that <s:selectItems> doesn't work.
Thanks in advance for any help.
Best regards,
jquery
