「p:autocomplete」ウィジェットを正常に機能させることができません...
ここに示すように、オートコンプリートウィジェットを使用しています...
<p:autoComplete id="abc" dropdown="true" value="#{testBean.parmMap['inputval']}" completeMethod="#{testBean.testList}" var="items" itemLabel="#{items.label}" itemValue="#{items}" converter="#{itemConverter}" ></p:autoComplete>
次のエラーメッセージが表示されます...
javax.el.PropertyNotFoundException:/index.xhtml @ 18,245 itemLabel = "#{items.label}":プロパティ'label'がタイプjava.lang.Stringに見つかりません
私はこのエラーを乗り越えることができませんでした。問題がどこにあるのかわからない -以下に示す関連コードのほとんどを含めました。あなたが私に提供できるどんな指導にも感謝します!
これがフェイスレットページ全体です-index.xhtml...

これが「アイテム」クラスです...
package aaa.bbb.ccc.war;
public class Item
{
private String label;
private String value;
public String getLabel()
{
return label;
}
public void setLabel(String label)
{

}
public void setValue(String value)
{
this.value = value;
}
}
これがItemConverterクラスです...

return refData;
}
}
これがTestBeanクラスです...
package aaa.bbb.ccc.war;

return refData.getParmMap();
}
public void setParmMap(LinkedHashMap<String, String> m)
{

refData.setParmMap(m);

}
}

}
return refData;
}
private static void storeRefData(RefData r)
{
FacesContext.getCurrentInstance().getExternalContext().getSessionMap().put("refData", r);
}
}
これがRefDataクラス(TestBeanで参照)です...

FWIW-これがpom.xml(primefaces依存関係を含む)です...
