Kevin,
Assuming your post doesn't have typo's, I think the JSP 1.2 spec
still requires the inner quotes to be escaped. I don't recall
that changing. Try changing:
<opf:orderDetail from="<%= request.getParameter("from") %>">
to:
<opf:orderDetail from="<%= request.getParameter(\"from\") %>">
^ ^
I have been bit by this numerous times.
