Hi Peter,
I came across the exact same problem myself, the OutputStream seems to be
called twice and the Servlet container (I use Tomcat) throws a
IllegalStateException. The problem is fixed simply by invoking the
declareDirectResponse method.
<snip>
aData.declareDirectResponse();
HttpServletResponse lRes = aData.getResponse();
// Setting content type and headers
lRes.setContentType(aContentType);
lRes.setContentLength(aWriter.toString().length());
lRes.setHeader("Content-type", aContentType);
lRes.setHeader("Content-Disposition", "attachment;filename = " + aFileName);
// Get the output stream from the response object
OutputStream lOut = lRes.getOutputStream();
// Using the output stream, push the contents contained within the
StringWriter to the
// user
lOut.write(aWriter.toString().getBytes());
lRes.flushBuffer();
</snip>

Actually, I'm getting more and more unhappy with the deprecation of
VelocityECSLayout. There seem to be many quirks that can't be fixed
in a clean manner. We might have to think about this a little more.

Could you please post some code snippets. How do you do the file
download? Directly from the action (you shouldn't do that) or do you
have a screen which does the download to which you redirect? I'm
getting a little scared by reading that you try to manipulate the
Servlet output stream by yourself. :-)

Henning
