我有一個由JAXB生成的集合，我想將它關聯到一個selectManyListbox以進行多選。selectManyListbox for jaxb collection
這裏是JSF：
<h:selectManyListbox value="#{field.textValueLookup.value}" size="5" >
<f:selectItems value="#{consultaController.getOpcionesLookup(field.queryField)}"/>
</h:selectManyListbox>
，這是JAXB

}
的問題是，所產生的JAXB類的收藏價值二傳手值的缺乏和TextValueLookup類generateb當提交selectManyListbox（ajax或form）時，會拋出以下錯誤：
Target Unreachable，'null'返回null：javax.el.PropertyNotFoundException ：/consultaCompleja/seleccionCamposFiltro.xhtml @ 39,18 value =「＃{field.textValueLookup.value}」：Target Unreachable，'null'返回null
任何解決方法？
