Gunnar Hillert commented on WW-771:
-----------------------------------
I have added a patch providing the following additional tag attributes:
cssErrorStyle and cssErrorClass
Furthermore, I have changed the 'simple' template to set the error style and/or
error class in case a field error occurs.
This is the behavior:
If a field error occurs and a cssErrorClass is set it will not override the
potentially set cssClass but rather add the cssErrorClass (As described by Matt
in ticket WW-771)
However, for a cssErrorStyle it will override the cssStyle in case a field
error occurs.
I hope this will cover the requested functionality.

> From Struts HTML taglib documentation about the errorStyleClass attribute:
> <snip>
> CSS stylesheet class to be applied to this HTML element if an error exists
> for it (renders a "class" attribute).
> N.B. If present, this overrides the styleClass attribute in the event of an
> error.
> </snip>
> Translated into WebWork's vocabulary: replace the style class of the element
> if there's a fieldError associated with its name.
> Such a feature makes it very easy to highlight the fields having an error
> using plain CSS and without any presentation logic involved.
