Re: Data validation, mapping, and error handling

Can you not still use client-side scripting once you've determined there's
an error?

Maybe there is a JSF keyword, but you are having trouble finding it, and I
certainly do not know enough to give you the answer. But if it was me, I
check to see if there's an error message and then change the class using
client-side scripting to get around the issue at hand.

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...
