Lookup jsf

Oi pessoal, eu tava tentando fazer um lookup em jsf com a tag selectOneListBox mas não ta dando certo, tipo eu tenho no meu bean

Por enquanto está fixo depois eu tenho que mudar mas, crio um SelectItem, seto o label e o value, adiciono num ArrayList e rotorno o array, no jsp

criei um selectOneListbox e no selectItems eu chamo estados, e ele me retorna o seguinte erro:

java.lang.IllegalStateException: Component javax.faces.component.UIInput@1210fb2 not expected type.  Expected: javax.faces.component.UISelectOne.  Perhaps you're missing a tag?
