You might want to debug a little bit (using `echo`) the classes of the toc and book results of XSLT.
At such an error, I would understand that both are either document objects or, at least, are roots of document objects hence not free elements.
Using something <j:set var="dtoc">${toc.detach()}</j:set> might actually help you to avoid that... at worst use ${toc.createCopy()} which is a deep clone.
Hope that helps.

I'm not an expert on jelly xml, but my guess is that its something to do with loading sample1.xml twice. Are you sure the parameters on the transform tag do what you think they do?

Hello,
When I am trying to process the following Jelly script I've got the error: [java] org.apache.commons.jelly.JellyTagException: file:/C:/Work/SDS/templates/sample1.xhtml:31:105: <x:transform> The node "[EMAIL PROTECTED] [Element: <h1 attributes: []/>]" could not be added to the branch "null" because: Cannot add another element to this Document as it already has a root element of: h1
[java] at org.apache.commons.jelly.impl.TagScript.handleException(TagScr
ipt.java:683)
Script:
<?xml version="1.0"?>
<j:jelly xmlns="http://my.uri.com"; xmlns:j="jelly:core" xmlns:x="jelly:xml"> ${systemScope.setProperty('javax.xml.transform.TransformerFact
ory','net.sf.saxon.TransformerFactoryImpl')}
${systemScope.setProperty('org.xml.sax.driver','org.apache.xer
ces.parsers.SAXParser')}
<html> <head> <title>The first sample</title> </head> <body>
<x:transform xslt="${basedir}/stylesheets/sample1-toc.xsl" xml="${basedir}/xml/sample1.xml" var="toc"/>
<x:transform xslt="${basedir}/stylesheets/sample1.xsl" xml="${basedir}/xml/sample1.xml" var="book"/>
<table border="1" cellspacing="0" cellpadding="0"> <tr> <td>Table Of Contents</td> </tr> <tr> <td> <!-- TOC --> <x:copyOf select="$toc"/> <!-- TOC --> </td> </tr> </table>
<table border="0" cellspacing="0" cellpadding="0"> <tr> <td> <!-- BODY --> <x:copyOf select="$book"/> <!-- BODY --> </td> </tr> </table>
</body> </html> </j:jelly>
If I use comment out second <x:transform var="book"/> and remove second <x:copyOf/> then the script works fine. Maybe somebody knows why?
