html:messages help
Hi,
I am having trouble getting messages to display using the html:messages
tag. I have tried to help myself and followed the struts docs but I
can't seem to get this to work. The html:errors tag works fine. Here's
what I am trying to do:
I have an action that is trying to add a global message if a certain
action is successful.
<code-snippet>
ActionMessages messages = new ActionMessages();
messages.add(ActionMessages.GLOBAL_MESSAGE,
new ActionMessage("mesg.pwResetSuccess"));
if (!messages.isEmpty())
saveMessages(request, messages);
forward = mapping.findForward(GLOBAL_FORWARDS.LOGIN);
</code-snippet>
As you can see I create a messages object, stick my message in it as
global and save it. This is pretty much verbatim from the struts user
guide. I ran this through a debugger and all code is being executed.
This forwards to a jsp page that has the following inside it:
<code-snippet>
<ul>
<html:messages id="message">
<li><c:out value="${message}" /></li>
</html:messages>
</ul>
</code-snippet>
When the browser renders the page I get no messages. Any ideas?
Thanks,
Ross

To answer my own question, in this case I was able to remove the
redirect attribute and everything works. If I couldn't do that I would
have had to stick the messages in the session.
Thanks,

Hi Daniel,
Ah yes, that was exactly it, thanks. It may have taken me a long time
to figure that out. To save me even more time what was your solution?
The global forward I am forwarding to looks like the following in
struts-config.xml:
<global-forwards>
<forward name="login" path="/login.do" redirect="true"/>
</global-forwards>
I want to display a message at the top using html:messages.
I seem to recall needing the redirect set to true but I can't remember
why. Is that affecting it?
Thanks,
Ross

Hi Ross,
I know this maybe can't make any sense but i got this problem once due
to some mistakes handling scopes.
Let me explain:
I had an Action instance that did some stuff and in case of errors,
put them all in the request and forward to the next view. But my next
view was a forward action (a global forward) to a jsp error page. So,
when the forward action was executed, the messages saved in the
request were lost, resulting in no error messages rendered in my jsp
page.
May this be your situation?
Hope that helped.
Cheers,
Daniel Silva.

This could be something. I do have the taglib definition but I am using
the el version, so mine looks like this:
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html-el"
prefix="html"%>
Would that make a difference? I will try it the other way.

Hi,
Thanks again but still not working. I tried as you suggested. I don't
think it is a problem with the <c:out> tag anyway because when I look at
what the browser gets I see
<ul>
</ul>
And not
<ul>
<li>
</li>
</ul>
Anyway, I will get the struts source and step through the html:messages
code, perhaps there is something fishy going on in there.

Try the following... Don't forget to import struts-bean.tld
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
I think it is better to use struts-tags when possible since they were designed for Struts.
<ul>
<html:messages id="message" message="true">
<li> <bean:write name="message"/></li>
</html:messages>
</ul>

Hi,
Thanks for the response, but no dice, still doesn't work. I changed the
jsp to the following:
<code-snippet>
<ul>
<html:messages id="message" message="true">
<li><c:out value="${message}" /></li>
</html:messages>
</ul>
</code-snippet>
I am using Struts 1.1 so I don't have access to addMessages().
Any other suggestions?
Thanks,
