Re: ActionMessage(s) + html:messages

[otisg <ot...@ureach.com>]

Hello,

I still haven't resolved the problem described in the original
email, so here is some sample code that should illustrate the
problem with ActionMessage(s) and html:message tags futher.

The code that uses ActionError(s) works when used with
html:messages tag.
The code that uses ActionMessage(s) does _not_ work with
html:messages tag, even though it looks like it should be
equivalent to the lines that use ActionError(s).

  // ActionErrors errors = new ActionErrors();
  ActionMessages errors = new ActionMessages();
  // errors.add(ActionErrors.GLOBAL_ERROR,
             new ActionError("error.auth.failure"));
  errors.add(ActionMessages.GLOBAL_MESSAGE,
           new ActionMessage("error.auth.failure"));
  // saveErrors(request, errors);
  saveMessages(request, errors);
  return mapping.findForward("failure");


I am using html:messages like this:

          <html:messages id="msg">
            <c:out value="${msg}"/>
          </html:messages>


The above JSP snippet works fine with ActionError(s) code above,
but _not_ with ActionMessage(s) code, which is also above.

Am I doing something wrong here?

Thanks,
Otis

Or change it to:

            <html:messages id="msg" message="true">
              <c:out value="${msg}"/>
            </html:messages>

and it should work.

You shouldn't have changed this part.  The difference between these two 
methods is the request attribute name under which the ActionMessages 
object is saved; read the JavaDoc for Action and the details for 
html:messages for the details, but if you use:
>           <html:messages id="msg">
>             <c:out value="${msg}"/>
>           </html:messages>

it will look for an ActionMessages saved with "saveErrors()", not 
"saveMessages()"
