Question

有人能帮我理解这里有什么问题吗？

这是来自Spring web flow项目的片段。我在中创建新对象订单并从数据库中获取表对象的列表视图状态标记。

    <?xml version="1.0" encoding="UTF-8"?>
<flow xmlns="http://www.springframework.org/schema/webflow"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/webflow
                    http://www.springframework.org/schema/webflow/spring-webflow.xsd">

    <input name="order" required="true" />

    <view-state id="chooseTable" model="flowScope.order">
        <on-entry>
            <set name="flowScope.order" value="new pizza.Order()"></set>
            <evaluate expression="pizzaFlowActions.getFreeTables()"
                result="viewScope.tables" />
        </on-entry>
        <transition on="chosenCreateOrder" to="bookedToOrder">
        <evaluate expression="order.setTable(flowScope.order)" />
        </transition>
        <transition on="chosenNoOrder" to="booked">
        <evaluate expression="order.setTable(flowScope.order)" />
        </transition>
        <transition on="cancel" to="cancel" />
    </view-state>

    <end-state id="cancel" />

    <end-state id="bookedToOrder">
    </end-state>

    <end-state id="booked">
    </end-state>

    <global-transitions>
        <transition on="cancel" to="cancel" />
    </global-transitions>
</flow>

带有与订单对象绑定的表单的Jsp文件，以及radiobuttons＆＃39;从 表格列表 中提取的值。

<html xmlns:jsp="http://java.sun.com/JSP/Page"
    xmlns:spring="http://www.springframework.org/tags"
    xmlns:c="http://java.sun.com/jsp/jstl/core"
    xmlns:form="http://www.springframework.org/tags/form">

<jsp:output omit-xml-declaration="yes" />
<jsp:directive.page contentType="text/html;charset=UTF-8" />

<head>
<title>Book a table</title>

</head>
<body background = "${pageContext.request.contextPath}/resources/plan.gif">
    <form:form commandName="order" class="box login">
    <input type="hidden" name="_flowExecutionKey" value="${flowExecutionKey}" />        
        <b>Choose table: </b>
        <c:forEach items="${tables}" var="place">   
           <form:radiobutton path="table" label="${place}" value="${place}"/>
        <br></br> 
        <br></br>   
        </c:forEach>
        <input type="submit" class="btnLogin" name="_eventId_chosenCreateOrder" value="Now choose Pizza" />
        <input type="submit" class="btnLogin" name="_eventId_chosenNoOrder" value="Just book a table" />
        <input type="submit" class="btnLogin" name="_eventId_cancel" value="Cancel" />
    </form:form>
</body>
</html>

订单类

public class Order implements Serializable {
private static final Logger LOGGER = getLogger(Order.class);
private int id;
private Customer customer;
private Set<Pizza> pizzas;
private Payment payment;
private Place table;

这里的问题是，在任何时候选择任何变体后，表单只是重新加载而且没有任何其他事情发生。

非常感谢任何帮助和提示。
