ap:dataTable 内の ap:commandButton で問題が発生しました。ボタンがバッキング Bean のプロシージャを呼び出しません。このボタンが機能しない理由を知っている人はいますか?
よろしくお願いします
ボタンコード:
<p:column headerText="Details" style="width: 10px;">
<p:outputPanel id="buttonDetail">
<p:commandButton icon="ui-icon-vwfList"
styleClass="colButton"
action="#{customerChangeHistoryHandler.selectHistoryElement()}"
id="buttonDetail"
update=":historyDetail"
title="GO!!!">
</p:commandButton>
</p:outputPanel>
</p:column>

public void selectHistoryElement(){

データモデルの Bean を RequestScoped にする方法はありますか?
