> The Anchor tag is providing a default value for href attribute when it should not.
> Previous versions of Struts2 did not do this, and in fact the documentation for the tag
also says there is no default value.
> However it is placing a default value of the current URL, rather than leaving the href
attribute off altogether.  (it is legal per HTML to not have an href attribute, and in fact
we had existing code that was trying to purposely leave it off, but now instead of being left
off, it is rendered with the current URL).
> I believe the problem was introduced with the changes related to WW-3037.   This block
of code precisely:
> {code}
>     @Override
>     protected void evaluateExtraParams() {
>         super.evaluateExtraParams();
>         if (href != null)
>             addParameter("href", ensureAttributeSafelyNotEscaped(findString(href)));
>         else {
>             //no href, build it from URL attributes
>             StringWriter sw = new StringWriter();
>             urlRenderer.beforeRenderUrl(urlProvider);
>             urlRenderer.renderUrl(sw, urlProvider);
>             String builtHref = sw.toString();
>             if (StringUtils.isNotEmpty(builtHref))
>                 addParameter("href", ensureAttributeSafelyNotEscaped(builtHref));
>         }
>     }
> {code}
> To preserve documented and previous functionality of allowing href to not be rendered
in the tag, the entire "else" block should be removed.
