Spring WebFlow2 JavaScript没有提交页面？

如果用户点击其中一个单选按钮，我正在尝试使用WebFlow2附带的Spring JavaScript来提交带有转换值的页面。我插入了我的javascript但该页面未在点击时提交？

JSP：

Answer 1

尝试为每一行添加不同的ID，如下所示：

    <td><form:radiobutton value="B" path="row" id="rowB" />Row: B<BR>
        <form:radiobutton value="A" path="row" id="rowA" />Row: A<BR>
        <script type="text/javascript">
              Spring.addDecoration(new Spring.AjaxEventDecoration({
                    elementId : "rowA",
                    formId : "customer",
                    event : "onChange",
                    params : {
                        _eventId : "loadSchools",
                        fragments : "body"
                        }
               }));
               Spring.addDecoration(new Spring.AjaxEventDecoration({
                    elementId : "rowB",
                    formId : "customer",
                    event : "onChange",
                    params : {
                        _eventId : "loadSchools",
                        fragments : "body"
                        }
               }));
        </script></td>

Answer 2

这是我的代码的一部分正在工作（表单被提交），它是一个选择而不是radiobutton但相同的想法。当您选择一个值时，它会自动提交表单并更新值：

<form:form commandName="dateRange">
...
    <select name="fyForDR" id="fyForDR" class='discretFont' style='margin-left:10px;margin-right:10px;'>
            <option value="" selected='selected'>Fiscal Year</option>
            <option value="2011" <c:if test="${fyForDR == '2011'}">selected="selected"</c:if> >FY11</option>
            <option value="2010" <c:if test="${fyForDR == '2010'}">selected="selected"</c:if> >FY10</option>
            <option value="2009" <c:if test="${fyForDR == '2009'}">selected="selected"</c:if> >FY09</option>
            <option value="2008" <c:if test="${fyForDR == '2008'}">selected="selected"</c:if> >FY08</option>
            <option value="2007" <c:if test="${fyForDR == '2007'}">selected="selected"</c:if> >FY07</option>
            <option value="2006" <c:if test="${fyForDR == '2006'}">selected="selected"</c:if> >FY06</option>
        </select>
        <script type="text/javascript">
            Spring.addDecoration(new Spring.AjaxEventDecoration({
                elementId: "fyForDR",
                event: "onchange",
                formId:"dateRange",
                params: {fragments:"body", _eventId: "setFy"}
            }));
        </script>
...
</form:form>

这是流程定义的一部分：

<view-state id="dateRangeForm" model="dateRange">
...
    <transition on="setFy" validate="false" >
                <set name="viewScope.fyForDR" value="requestParameters.fyForDR"/>
                <evaluate expression="dateRange.setStartDate(dateRangeService.getFyStartDate(viewScope.fyForDR))"></evaluate>
                <evaluate expression="dateRange.setEndDate(dateRangeService.getFyEndDate(viewScope.fyForDR))"></evaluate>
    </transition>
...
</view-state>
