[Seasar-user:11122] ボタンを1回押したら「二重サブミットされました」

[Junichi Kato]

加藤です．

えっと，今度は以下のような例外に見舞われております．

サブアプリケーション内での遷移なのですが，
doOnceConfirmを1回だけ押すと例外が発生します．

ソースを追っかけますと，getPreviousTokenが，nullを返している．
subAppScopeがnullになっていますがこの状況は何が原因と考えられるでしょう
か？

ちなみに，HTMLには複数のフォームがあって，各フォームの中には複数のdoOnce
メソッドがあります．

    protected static String getPreviousToken(final FacesContext context)
{
        final Map subAppScope = SubApplicationScope.getContext(context);
        if (subAppScope == null) {
            return null;
        }
        return (String) subAppScope.get(PREVIOUS_TOKEN);
    }
