Hi Aaron: I need to keep the original domain object for reference in the test.jsp, hence I use flash().
Yes, by changing the stripes.properties file I can get it working, but it's still a little bit weird to me that I can not detect if there's any message available at page rendering time. The other shortcoming for property file is that I may have different layout for messages in different jsps, So simply specify a single style for all of them is not an appropriate option. I will still working on it to see if there's any solution. Thank you for your help.

The easiest thing to do is drop the <c:if> and <div class="success"> so you just have <s:messages /> in your JSP. Then edit StripesResources.properties and change the stripes.messages.* properties to whatever you want to wrap the messages with. Maybe something like this for what you're trying to do: stripes.messages.header=<div class="success"><ul> stripes.messages.beforeMessage=<li> stripes.messages.afterMessage=</li> stripes.messages.footer=</ul></div> Aaron Hubert Yang wrote: > Hi all: > > In one of my events I first add some message, and then redirect the page by > flash scope: > > getContext().addMessage(“…”); > return createRedirect(“/jsp/test.jsp”).flash(this); > > And in the jsp file above, I try to display the message if any: > > <%@ taglib prefix="s" uri="http://stripes.sourceforge.net/stripes.tld"; %> > <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"; %> > //… > <c:if test="${!empty actionBean.context.messages}"> > <div class="success"><s:messages /></div> > </c:if> > //… > > However, a NullPointerException is thrown after doing this, I debug into > Stripes code only find that > the returned FlashScope is null: > ActionBeanContext.getMessages(ActionBeanContext.java:191) > > But if I remove the c:if tag and use <s:messages /> only, everything works > fine. > > Is there any logical explanation for this?
