Re: Data validation, mapping, and error handling

Joe

The problem is that, using server-side
validation, I haven't found the JSF keyword (if one exists) that will
tell a field to use an alternate style if the field is in error.

One of the nice things about ASP.NET is that Client Side and Server Side
validation is combined (out of the box) using the ASP.NET Validator
controls, so you can easily set the CSS attribute of the field in error from
wherever you wish (client side generated JavaScript or C#/VB code behind).

Use CSS to change the background color and the text color.

Yup, I understand that, Michael. I've already done that, creating a
class for error messages and a class for input fields in error. And on
client-side validation, it's easy to define the class to apply to a
field when an error occurs. The problem is that, using server-side
validation, I haven't found the JSF keyword (if one exists) that will
tell a field to use an alternate style if the field is in error.

I would have created one, but the JSF implementers didn't ask me... <grin>
