I FIND THE PROBLEM! It is not mine, but the tag. See the below 10/21/2002 11:10:03 AM, "Karr, David" <[EMAIL PROTECTED]> wrote:

I use the script instead as I did in the controller. The data is shown correctly. The code is the followings: <% List list = mbox.getList(); for(int i = list.size(); --i >= 0;){ MessageHeader header2 = (MessageHeader)list.get(i); %> <td><%=header2.getFrom() %></td> <td><!-- c:out value="${header.from}"/ --></td> <td><!-- c:out value="${header.subject}"/ --></td> <td> </td> </tr> <!-- /c:forEach --> <% } %> At the point, I can say the tag doesn't function properly for this case. Is a bug fixed in the most recent release, or I shall not use tag for now? >I'm only suggesting doing this to narrow down which part is going wrong, the >list, or the items. > >> >It could be handy to step through this in your debugger and >> inspect the >> >session data for these objects. >> >> I don't have any JSP debugger.
