问题描述

我在Springs Web Flow中遇到问题。如果用户点击表单提交按钮，我将在我的bean中具有 RIGHT 值。

I am having a issue with Springs Web Flow. If the user clicks on the form submit button I will have the RIGHT values in my bean.

性别字段的示例将为MALE或FEMALE。但是，我然后添加了一个 AjaxEventDecoration 来提交更改性别下拉框，这是一个真正的形式：select ，在bean中将获得值为sex，这是elementId。以下是我的代码，你可以查看它，让我知道你的想法...我需要尽快解决这个价值...

Example the sex field will be MALE or FEMALE. But I then added a AjaxEventDecoration to do a submit on change of the sex dropdown box which is really a form:select and in the bean I will get the value "sex" which is the elementId. Below is my code can you please review it and let me know what you think... I need to fix this value ASAP...

推荐答案

您没有关闭< / b> 之后的活动，但< / n> 。导致一些奇怪的问题，如你正在使用的

you don't have any closing </b> after "Active" but </n>.
these things some times can lead up to weird issues like the one you are having

修复它，再试一次

我找到一个解决方案pb：基本上删除你的选择的装饰和ajax事件，这样做：

I found a solution to you pb: basically remove the decoration and ajax event on your select and do it this way:

<tr>
    <td><font color=red><form:errors path="sex" /></font><b>Sex:</b></td>
    <td><form:select path="sex" id="sex" required="true" data-dojo-type="dijit/form/Select" onchange="Spring.remoting.submitForm('sex', 'customer', {fragments:'body', _eventId: 'loadSchools'}); return false;">
            <form:option value="MALE" label="MALE" />
            <form:option value="FEMALE" label="FEMALE" />
        </form:select>
   </td>
</tr>

似乎有一些选择装饰的问题...我会尝试看看我是否可以找到另一种方式，但我测试了这个，它的作品

it seems like there are some issues with select decoration... I will try to see if I can find another way, but I tested this and it works
