java.lang.IllegalStateException通过Primefaces的commandButton

Question

进入最终状态时，这是我的流量（简化）：

<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> 

和我的facelet（也被简化）：

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

只要作为“customerCreated.xhtml”不包含啊：表格，一切似乎都很好。但是，如果它确实存在，但以下情况除外得到投掷：没有Ajax的commandButton：

这不使用常规的h当发生（用F时：AJAX，只是什么都不会发生在客户端）。

使用： - 春4.2.0 - 春天的Webflow 2.4.2 - Primefaces 5.2 - 钻嘴鱼科2.2.9

Answer 1

你明确执行 '操作' 与controller.createCustomer（客户）

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

因此，这不是一个真正的最终状态。将其更改为动作状态，然后转换为空白/虚拟结束状态。
