Retrieving specific form validation error messages
In a JSP containing a form, what is the easiest way to see if a form
validation error message exists for a particular, say, html:text field,
when that page is processing after form validation has failed? For
example, what if you wanted to present the messages field by field
instead of all together at the top of the page? I assume the error
messages are keyed according to the value of the "property" attribute
for each field, or something similar?
Thanks,
Erik

You could do something like this
<td><html:text property="login"/></td><td class="error"><html:errors
property="login"/></td>
<td><html:password property="password" redisplay="false"/></td><td
class="error"><html:errors property="password"/></td>
Thanks,

Thanks Niall.
Now, what I need is to change the style of the prompt text beside the
field, not the field itself, or else perhaps the td that houses both the
prompt and the input. But, you have given me an idea . . . Perhaps I
could extend the bean:message tag to act in a similar way? I would
appreciate knowing if you think that is sensible.
I'll check out the bug report.
Thanks,
Erik

Theres an open bugzilla ticket requesting this kind of feature:
http://issues.apache.org/bugzilla/show_bug.cgi?id=20784
Haven't really had time to look at it, but it has patches attached.
I also posted an extension to the <html:text> tag on my web site which
highlights error fields.

This is what I came up with:
<c:set var="foo" value="valueA"/>
<logic:messagesPresent name="org.apache.struts.action.ERROR"
property="currentField">
<c:set var="foo" value="valueB"/>
</logic:messagesPresent>
. . . render the prompt for currentField, placing <c:out
value="${foo}"/> where necessary (this could be a css class or font
color, etc.) , , ,
I am doing this for each field. Please let me know if there is a better way.
Thanks,
Erik

Re: Retrieving specific form validation error messages
Posted by Erik Weber <er...@mindspring.com>.
I see that the ActionErrors object is stored as a request attribute
under the key "org.apache.struts.action.ERROR".
I would like to set a different CSS class for each <td> containing a
field that has a property that is keyed in the ActionErrors instance. In
pseudocode:
begin "username" field;
if (ActionErrors instance exists and ActionErrors instance contains any
ActionErrors for the "username" property) {
open td with class set to "style B";
print prompt for username field;
print username field;
close td;
}
else {
open td with class set to "style A";
print prompt for username field;
print username field;
close td;
}
. . . and so on, for each field. This seemingly could get to be a lot of
code. Any Struts/JSTL tag tricks I can use?
Thanks,
Erik
