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
