I'm getting "No active conversation context" after upgrade to Seam 2.0

Looks like this one is caused by changes to page.xml files in Seam 2.0.
It now uses different XSD.

Updating page.xml prologue

to

<page xmlns="http://jboss.com/products/seam/pages"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://jboss.com/products/seam/pages http://jboss.com/products/seam/pages-2.0.xsd">

didn't fix it.

Here is exception stack

Caused by: org.dom4j.DocumentException: Connection refused: connect Nested exception: Connection refused: connect

I missed XSD update to pages.xml. It works now.
