これに似たいくつかの例外が発生していますが、私の場合は、さらに別の問題の結果だと思います。
環境: JBoss AS 7、JSF (Mojarrah + Primefaces 3.2)、JPA 2 (Hibernate)、EJB 3.1、CDI
非常によく似た構造のビューが 4 つあります。そのうちの 3 つは問題なく動作しますが、最後の 1 つはこの問題を抱えています。p:inputText(p=Primefaces) とp:dataTableコンポーネントで構成されます。
<p:inputText id="barcode" label="Barcode" value="#{testBean.barcode}"
required="true" validator="#{testBean.validateBarcode}">
<p:ajax process="@this" update="@form" />
</p:inputText>
<p:message for="barcode" />
<p:dataTable [...]/>
Enterユーザーがバーコードを入力したときに（キーを押すか、テキストフィールドを離れると）、Ajax経由でフォームが送信されることを期待しています。私のバッキング Bean は拡張モード@Named @ViewScoped @Statefulを使用しています (この回答の 1 つに記載されているように)。EntityManager
問題:どうやらフォームが同時に 2 回送信されるようです。
- Ajax POST リクエストとして -> スレッド #5 で
- プレーンな POST リクエスト (非 Ajax) として -> スレッド #6 で
私のログファイルの状態：
21:58:09,294 Information [net.svv.servlet.RequestLogger] (http--127.0.0.1-7080-5) POST /tat/tat/test.jsf
21:58:09,302 Information [net.svv.servlet.RequestLogger] (http--127.0.0.1-7080-6) POST /tat/tat/test.jsf
次の例外が発生します。
21:58:09,334 WARN [com.arjuna.ats.jta] (http--127.0.0.1-7080-6) ARJUNA016029: SynchronizationImple.afterCompletion - failed for org.jboss.as.ejb3.component.stateful.StatefulSessionSynchronizationInterceptor$StatefulSessionSynchronization@67dc20fd with exception: java.lang.IllegalStateException: JBAS014531: Cache entry {[-106, 108, 121, 57, -117, -54, 77, -75, -66, 78, -95, 39, 21, -84, -2, 118]} is not in use
数回、時には〜20回。
次に、HTTP 応答:
21:58:11,892 Information [net.svv.servlet.RequestLogger] (http--127.0.0.1-7080-5) response: 200 text/xml;charset=UTF-8 (2598 msec)

私が理解しているように、ビューは同じセッション内で 2 回要求され、例外が発生します。私の質問は、Enterキーを押したときにフォームが 2 回送信されるのはなぜですか? また、この動作が 4 つのビューの 1 つだけで発生するのはなぜですか? <p:inputText />(他のバーコードには同じコンポーネントがあります)
ps: EnterJavaScript を使用してキー イベントをチェックする可能性があることは承知しています。そのため、それを回避する方法の問題ではなく、フォームが 2 回送信される理由の問題です。また、使用するバーコード スキャナーの一部は、Enterchar を送信してデータを送信します。
pps: Ajax フォームの送信で、 を押したときに再送信されないようにしたいだけですF5。
ストーリー全体を読んでくれてありがとう ;)
