Enhanced errors tag

[Martin D Bayly <ba...@jpmorgan.com>]

A useful enhancement to the <html:errors/> tag would be to have a single message
 header/footer as well as an error block header and footer.
This enables you to keep your message strings free of html markup such as the
<li> shown in the examples.

eg.
errors.header=<h3><font color="red">Validation Error</font></h3>You must correct
 the following error(s) before proceeding:<ul>
errors.footer=</ul><hr>

with the extension of:

error.header=<li>
error.footer=</li>


The attached is a version of our ErrorsTag (copied from the struts errorstag)
incorporating this change

(See attached file: ErrorsTag.java)

There is an html:messages tag that is basically the
same as html:errors except it iterates over messages
and errors so you can remove the html from the message
resources.  There are the classes ActionMessages and
ActionMessage for general messages like "Record has
been deleted.".  ActionErrors is a subclass of
ActionMessages and ActionError is a subclass of
ActionMessage.  I'm working on adding some
documentation with code examples for this.

  <h3><font color="red"><bean:message
key="errors.header"/></font></h3>

  <ul>
  <html:messages id="message">
     <li><bean:write name="message"/></li>
  </html:messages>
  </ul>

  errors.header=Validation Error

or

  <html:messages id="message" header="errors.header"
footer="errors.footer">
     <li><bean:write name="message"/></li>
  </html:messages>

  errors.header=<h3><font color="red">Validation
Error</font></h3>
    You must correct the following error(s) before
proceeding:<UL>
  errors.footer=</ul><hr>

The header and footer attributes are optional.

I think a new tag that allows you to not put HTML in your resource file
already exists in post 1.0 Struts in the form of the <html:messsage(s)> tag.
It can be used in place of <html:errors>. The errors class is now a subclass
of a message class.
