Don Brown commented on WW-771:
------------------------------

This patch applies fine, but is missing tests.  Could you add a few tests, preferrably one per tag?

> 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.
