具有验证错误的JSF PRG [英] JSF PRG with validation error
问题描述
我正在将JSF与PRG模式一起使用. (在我的导航规则中使用).
I'm using JSF with the PRG pattern. (use in my navigation rules).
问题是当我收到验证错误(例如:用户未设置必填值)时，重定向未完成(即，帖子后跟随同一页面).
The problem is that the redirect is not done (i.e. a post followed by a get of the same page) when I got validation errors (ex : the mandatory value isn't set by the user).
场景是:
-
用户未输入强制值并提交表单
user doesn't put the mandatory value and submit the form
验证错误，并且显示相同的视图并显示错误 消息(无PRG)
validation error occurs and the same view is shown with an error message (no PRG)
用户设置强制值并提交==>转到下一页 (使用PRG)
the user set the mandatory value and submit ==> GO to the next page (with PRG)
用户单击后退按钮=>问题，因为在 第2步.==>在Firefox中显示文档过期"屏幕
The user click back button => problem because no PRG was done in the step 2. ==> Got a "Document Expired" screen in Firefox
有人可以帮我吗?
谢谢.

推荐答案
只需通过ajax提交表单.只需添加
Just submit the form by ajax. It's a matter of adding
<f:ajax execute="@form" render="@form" />
到命令链接和按钮.如果您使用的是<h:message(s)>，那么我认为它们的格式完全相同，否则您需要将其客户端ID添加到render.
to the command links and buttons. If you're using <h:message(s)>, then I assume that they are in the very same form, otherwise you need to add their client IDs to the render.
通过ajax提交表单时发生的验证错误不会生成历史记录.
Validation errors while submitting the form by ajax won't generate history.
