I came up with a StaticFilter (from http://issues.appfuse.org/browse/APF-431)
that seems to work (see code below). However, it causes another issue for
me. In my SiteMesh decorator, I'm including a messages.jsp that has calls to
the valueStack:

<%-- ActionError Messages - usually set in Actions --%>
<s:if test="hasActionErrors()">
  <div class="error" id="errorMessages">  
   <s:iterator value="actionErrors">
     <c:url value= "
       alt="<fmt:message key="icon.warning"/>" class="icon" />
    <s:property escape="false"/><br />
   </s:iterator>
 </div>
</s:if>

<%-- FieldError Messages - usually set by validation rules --%>
<s:if test="hasFieldErrors()">
  <div class="error" id="errorMessages">  
   <s:iterator value="fieldErrors">
      <s:iterator value="value">
        <c:url value= "
          alt="<fmt:message key="icon.warning"/>" class="icon" />
        <s:property escape="false"/><br />
      </s:iterator>
   </s:iterator>
 </div>
</s:if>

When I return a static page, this JSP causes issue:

java.lang.NullPointerException
    at org.apache.struts2.views.jsp.TagUtils.getStack (TagUtils.java:58)

This works fine when I request a Struts Action. Is there any way to check
for the stack in my messages.jsp?

Thanks,

Matt
