There is no way to display success message(s). [SPR-2657]

There is no way to display success message(s) like struts' ActionMessage. Spring should provide Messages inteface in a similar way of Errors and related tag libraries.

Hi Daigo

I'm not quite sure what you mean with this issue; can you please explain a little more, perhaps supplying a use case?

If you want to display data upon sucess, you can put the data that you want displayed in the ModelAndView.

Cheers
Rick

Hi Rick

Actually I can set message to ModelAndView. However, I can't handle following issue cleverly.

1. I can't use LocaleResolver like Errors.
2. I want to use same way as spring:hasBindErrors to handle message, so I need spring:hasBindMessages.

Sample code:

<spring:hasBindMessages name="command">
<c:forEach var="msg" items="${errors.globalMessages}">
<span class="message"><c:out value="${msg}"/></span>
</c:forEach>
</spring:hasBindMessages>

I would be also interrested with this evolution for a secondary purpose:
I want to display warning messages on validation:

In fact, I want to warn (or inform) users about some validation problems (that are not critical, not errors in facts). if the user submit the form again with no changes, I want to perform the submit.

Hi,

This is one area where Struts is superior IMO and I wish Spring MVC would offer functionality similar to Struts' ActionMessage. (In my opinion good success messages are just as important as good error messages :-)
Besides providing a common infrastructure for handling error AND success messages in a standard way, it would also be great if those messages would survive redirects. Right now I am using the approach that is implemented in Matt Raible's Equinox. (Using a custom filter --> org.appfuse.web.MessageFilter).

Also, on a side note - would it be wise to have messages support for spring core? In quite a few cases my service layer methods need to pass back messages and I wonder if that is something to 'standardize' instead of rolling your own approach?

Thanks!

It will be very useful to have some comment framework for messaging besides just errors. Are there any plans for this issue?

I also need this feature. In the meanwhile I think we'll be developing (or borrowing) a custom one.

SWF appears to have this feature : http://static.springsource.org/spring-webflow/docs/2.3.x/reference/htmlsingle/spring-webflow-reference.html#view-messages.
Would be interesting to 'downgrade' it to Spring MVC ?

JSF has a similar feature (http://wiki.apache.org/myfaces/Displaying_Errors/Infos/Warnings_in_JSF_Pages).

<h:messages globalOnly="true" errorClass="errorMessage" infoClass="infoMessage"/>

Here's the API to add an info message to the queue :

getFacesContext().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_INFO, summary, null));

Seam 2 (works on top of JSF) has a simple API for info messages, and a less simple for ERROR/WARN messages (http://docs.jboss.org/seam/2.2.2.Final/reference/en-US/html/framework.html#d0e8463)

addFacesMessage("User #{user.username} already exists");

Thanks !
