Artur,
Somehow I couldn't move the the productId declaration & initialization before the
<Product> tag because this would move it to class level and 1.) the
<xsp-request:get-parameter> tag must be used within the root element of the generated
document (for some reason) and 2.) I get a NullPointerException when I try to use
request.getParameter at the class level. I have *very* little knowledge of the
request object and its XML logicsheet wrapper (I'm a newbie :-), so I unfortunately
can't shed any light on the exact reasons for these things.
HOWEVER: I tried the <xsp:init-page> tag under the <xsp:page> tag (before the
<Product> tag) and it worked!! The productId declaration now comes first in the
generate method so the attribute value can be computed with no problem.
Thanks Artur! :-)
