Hey Stephen, When using tags, you always keep spacing between the tags. The body of a c:forEach is often used for displaying output, so it has to output everything between it's tags. In your case that's only whitespace and newlines, but they still get output. What you might want to try is set the page buffer size a bit larger, so that your computation can always complete without flushing the buffer.
Try: <%@ page buffer="sizekb"%> According to spec, size normally reads 8 making the buffer 8kb. Try a larger size and see if that fixes the problem. Grtz, Martin PS Put that statement at the top of your page... > -----Original Message----- > From: Stephen Letschin [mailto:[EMAIL PROTECTED] > Sent: donderdag 12 februari 2004 6:30 > To: Tag Libraries Users List > Subject: RE: Problems with c:forEach and c:redirect > > > You are correct that the code is only doing computation (or > at least that is all I want it to be doing).
