私はこれを私のfaces-config.xmlに持っています：

<navigation-rule>
    <from-view-id>*</from-view-id>
    <navigation-case>
        <from-outcome>login</from-outcome>
        <to-view-id>/login.xhtml</to-view-id>
        <redirect/>
    </navigation-case>
    <navigation-case>
        <from-outcome>index</from-outcome>
        <to-view-id>/index.xhtml</to-view-id>
        <redirect/>
    </navigation-case>
</navigation-rule>

このページのいずれかに移動すると、次の例外が発生します。

行 1270 ( 2.2.1 では1200 ) は

FlowHandler fh = ctx.getApplication().getFlowHandler();

null を返し、次の行で NullPointerException を引き起こします。Glassfish 4.0.0、JDK 1.7.0_40、JSF 2.2.4 (2.2.1 は編集前でしたが、Glassfish に 2.2.0 があるとは知りませんでした)、Ubuntu 12.10 64 ビット。どうしたの？

別のエラーを修正した後、このエラーを見つけました。

アーティファクトから CDI ライブラリを除外しました。含めることはアイデアによって提案されました。
