Highlighting a field with a validation error in struts 2
Hi,
I'm trying to figure out how apply a class or some kind of style to a
input field when there is a validation error in struts 2. I think this
is a fairly common thing (apply a highlighted background color to an
errored field to focus the user's attention) but it does not seem to be
supported with the canned struts2 themes. Am I missing something, or
would I have to override the themes myself to achieve this kind of
functionality? Is there some other way I am missing? Thanks.

Afaik no theme does provide this, you have to write your own theme (actual for
this input field only) to do this - its really easy to do that.

If we use "simple" theme, then also can we make that?

Hi,
I think the easiest way would be to copy from struts2-core-xx.jar the
validation.js based on the theme and put it in your source package folder .
So example I took template/css_xhtml/validation.js from struts.jar and I
modified the javascript function:
function addError(e, errorText)
{
}
Here the 'e' is the form element so you can easily style it with javascript.
This applies to the Struts 2.0.11.2, I don't know about newer versions
but I think you can do the same.
See here about Overriding Templates:
http://struts.apache.org/2.0.12/docs/template-loading.html
Best regards,
Andras.

Sorry if this is a dupe; something funky is happening.

You should be able to use CSS selectors to get child elements of an element of a given style. That said, it'd be easier to modify the templates to provide whatever IDs you need. See below.

Oh, I guess I did that; sorry. Been so long I thought it was part of the framework :) I guess I modified the templates to add some IDs; I have a patch that I haven't applied yet because I keep forgetting.

I took a look around, and I can't seem to find any way to select an
input that has an error associated with it using css. The samples I've
looked at have ways to style the error message text, the label, etc, but
no way to style an input. I'm not seeing this "red border" either...
does anyone recall which theme provides this?
Thanks,
-Adam

Highlighting the entire row currently involves more CSS selectorship than necessary, and I haven't gotten around to applying my patch that provides more DOM names and ids yet.

I generally just override the supplied CSS (which does things like giving text boxes with errors a red border already, IIRC). Highlighting the entire row currently involves more CSS selectorship than necessary, and I haven't gotten around to applying my patch that provides more DOM names and ids yet.
