My form uses the Struts validator. One of its fields is 'required' and I
want the error message to show up alongside the field when the form is
redisplayed. There may also be general errors and I want these to be listed
at the top of the page. Problem is, the field specific error (created by
the validator framework) gets displayed alongside the field (correctly) AND
as a general error at the top of the page! I don't understand this; the
error message must be associated with a field property otherwise it wouldn't
show up alongside the field, so why is it also being treated as a general
error?
When you ask a JSP tag (html:messages or html:errors) to iterate
through errors without specifying a property, it iterates through all
messages; basically, you are just guessing wrong as to its default
behavior.
To get the behavior you want, one must specify as the property the
String literal used for global errors, that is:
org.apache.struts.action.GLOBAL_MESSAGE
It would be good to extend those JSP tag implementations to have
another attribute which basically meant only show global messages
so that you wouldn't have to know that literal value. In fact, I
just filed an enhancement ticket in Bugzilla about it:
http://issues.apache.org/bugzilla/show_bug.cgi?id=34489
I don't have time to write the patch right now, but as noted in the
ticket, this would be a pretty easy one for someone interested in
volunteering some time.
