Netui:error tag uses deprecated ActionError

Question

Can anyone tell me if there's a good reason why netui:error tag refers to the deprecated ActionError as opposed to ActionMessage?
It means I cannot do this as I get a ClassCastException:
<pre>
public ActionErrors validate(ActionMapping mapping, HttpServletRequest request) {
ActionErrors errors = new ActionErrors();
errors.add("test", new ActionMessage("someError"));
return errors;
</pre>
Instead I am forced to use a deprecated class. As ActionError inherits from ActionMessage, I can't really see why it is referenced.

I also encountered the same issue when I was working with this issue. I could not figure out how to do it so I came with a work around maybe this will help you.
In my JSP I use the following code:
<%
// this part gets the i18n messages which netui:errors tags are not capable of
ActionErrors actionerrors = (ActionErrors)request.getAttribute("org.apache.struts.action.ERROR");
if(actionerrors != null)
%>
<i18n:getMessage messageName="errors.header" />
<%
Iterator it = actionerrors.get();
while(it.hasNext())
ActionError e = (ActionError) it.next();
%>
<i18n:getMessage messageName="errors.prefix" />
<i18n:getMessage messageName="<%=e.getKey()%>" />
<i18n:getMessage messageName="errors.suffix" />
<%
%>
<i18n:getMessage messageName="errors.footer" />
<%
%>
