## Description

A tag that creates an HTML <a/> element, that when clicked makes an asynchronous request(XMLHttpRequest). The url attribute must be build using the <s:url/> tag.

There's a bug in IE6/IE7 which makes impossible to use the target's attribute with a parent Div, because such Div's content's are overwritten with the tag's loadingText. Resulting in an "undefined" message in the content's, instead of the result of the request.

One possible alternative is to set showLoadingText="false" and set the indicator attribute to an element showing the desired loading text or image (outside the div).
