Greets,
I'm trying to use the xsp-request logicsheet in my code and am
running into an odd error. Basically, if I wrap it in <xsp:expr/> and
use it in the body of the page, it'll work fine, but if I use it in the
<xsp:logic/> section, it throws a mess of errors. My code seems to
conform to the code at
http://xml.apache.org/cocoon/userdocs/xsp/request.html
(which is down now, but the google cache of it works).
Any clues would be appriciated.
The URL I'm using is :
http://localhost:8080/cocoon/mount/shopping-list/edit/store.html?store-name=foo
which directs to this XSP sheet.
Here's the code :
<?xml version="1.0"?>
<?cocoon-process type="xsp"?>
<xsp:page language="java"
xmlns:xsp="http://apache.org/xsp";
xmlns:xsp-request="http://apache.org/xsp/request/2.0";>
<xsp:logic>
String store_name = <xsp-request:get-parameter
name="store-name"/>;
</xsp:logic>
<store>
<store-name><xsp-request:get-parameter
name="store-name"/></store-name>
</store>
</xsp:page>
which fails. If I get rid of the <xsp:logic> section, it works fine.
the top-most exception is :
DEBUG (2002-07-29) 10:45.47:757
