I implemented something that I think is relatively slick today, so I
thought I'd share the idea.
First, a change was requested to suffix all our field labels with
colons. We already had this structure:
<th><bean:message key="SomeForm.someField"/></th>
<td><html:text property="someField"/></td>
I created a LabelTag taglib that (currently, but not necessary)
subclasses MessageTag.
It, of course, satisfies the request to suffix with a colon such that
our message resources (now in the database) are not changed, and the JSP
does not have colons. But, I figured why stop there, so I dug through
ValidatorResources and added in an asterisk if the field is required,
and then dug through ActionErrors and turned the field red (using CSS
classes and a <span>) if the field was in error.
This is a feature I've been thinking of for a while, and I'm sure others
have implemented similar features, but its such a big enhancement that I
felt like sharing it!
I'm not sure if this is worthy of making more generic and contributing
though. Thoughts? Its dependent on your forms subclassing
ValidatorForm and validation.xml be used appropriately, and it also
relies on field labels adhering to the <form name>.<field name> syntax
and be stored in the message resources.
