Thank you! That was exactly the problem (getter was doing something it shouldn't).

Given that both the action bean and the jsp are both single threaded to the current request, it is probably not a real concurrency issue (unless you have a background thread and a singleton, which I doubt). Anyway, perhaps your getter method, actionbean.getShortList() has some logic in it that is changing the list and/or its contents? I think you probably have public List<T> getShortList() { List<T> x = findStuffFromDB_OrDoSomethingToProduceList(); return x; } When essentially what you need is: private List<T> shortList; public List<T> getShortList() {return this.shortList}; public Resolution yourEvent() { shortList = findStuffFromDB_OrDoSomethingToProduceList(); return new ForwardResolution("/WEB-INF/your-jsp.jsp"); } Alternatively you could put the shortList= bit in an @Before method.. Problems like this one are easy to troubleshoot by running your container in debug mode. Also the howto on unit testing with MockRoundtrip is a really big time saver.

Here are the (hopefully) relevant code snipites: In the JSP: <s:form beanclass="accounts.actions.ShowStatementActionBean"> <c:forEach items="${actionBean.shortList}" var="inv" varStatus="loop"> <tr> <td>${inv.line.invoiceNum}</td></tr> <tr><s:text name="shortList[${loop.index}]"></s:text></tr> </c:forEach> </table> </s:form> The result is this exception: WARNING: ApplicationDispatcher[/Public] PWC1231: Servlet.service() for servlet jsp threw exception java.util.ConcurrentModificationException at java.util.AbstractList$Itr.checkForComodification(AbstractList.java:372) at java.util.AbstractList$Itr.next(AbstractList.java:343) at org.apache.taglibs.standard.tag.common.core.ForEachSupport$SimpleForEach Iterator.next(ForEachSupport.java:149) at org.apache.taglibs.standard.tag.common.core.ForEachSupport.next(ForEachS upport.java:171) at javax.servlet.jsp.jstl.core.LoopTagSupport.doAfterBody(LoopTagSupport.ja va:326) .... I'm fairly new to Stripes (and JSP development in general) so I'm sure it's something simple but I can't seem to figure out what..
