Spring 通过Primefaces命令按钮进入结束状态时发生java.lang.IllegalStateException

这是我的流程（简化）：

在没有Ajax的情况下使用常规的h:commandButton时不会发生这种情况（在使用f:Ajax时，客户端不会发生任何事情）

使用： -Spring 4.2.0 -SpringWebFlow 2.4.2 -Primefaces 5.2

---

-Mojarra 2.2.9

您可以清楚地使用controller.createCustomer（客户）执行“操作”

---

因此，这并不是真正的结束状态。将其更改为动作状态，然后转换为空白/虚拟结束状态

为什么使用SpringWebFlow而不是JSF2.2的内置Faces流？我可以理解，如果仍然使用旧的JSF2.0/2.1，为什么会使用SWF，但这里不是这样。或者您只是没有意识到新的JSF2.2 Faces流特性？如果第二个按钮失败，您将其更改为

h:commandButton

，但仍然失败，那么它与PrimeFaces无关，而是纯JSF/SWFNo，当使用h:commandButton时，一切都正常，这就是我们目前的做法。关于Facesflow，我们不能使用它们，因为WebSphere是……特殊的：我也尝试过这个，但没有改变任何事情。甚至尝试通过多个操作状态进行路由。@user3580311尝试在任何地方将“customer”显式定义为“flowScope.customer”。但这可能是一个bug。我建议您进入堆栈跟踪并分析异常的内部原因

<view-state id="create" view="createCustomer.xhtml">
    <transition on="create" to="end">
        <evaluate expression="controller.validateCustomerFilled(customer)"/>
    </transition>
</view-state>

<end-state id="end" view="customerCreated.xhtml">
    <on-entry>
        <evaluate expression="controller.createCustomer(customer)"/>
    </on-entry>
</end-state>

<p:commandButton value="Test Ajax" action="create" update="content, messages"/>
<p:commandButton value="Test No Ajax" action="create" ajax="false"/>

java.lang.IllegalStateException: The current state 'end' of this flow 'customer/create' is not a view state - view scope not accessible
