xxforms:variable not working

mschlossberg
I am finding a problem trying to use the <xxforms:variable> element.  Here's an
example.

Given this "cats.xml" data file (granted all the namespaces are not necessary):

<?xml version="1.0" encoding="UTF-8"?>
<cats xmlns="" xmlns:ev="http://www.w3.org/2001/xml-events"
xmlns:xforms="http://www.w3.org/2002/xforms"
xmlns:xhtml="http://www.w3.org/1999/xhtml"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xxforms="http://orbeon.org/oxf/xml/xforms">
        <cat color="brown" gender="F">Duchess</cat>
        <cat color="calico" gender="F">Princess</cat>
        <cat color="black" gender="M">King</cat>
        <cat color="tiger" gender="M">Prince</cat>
</cats>

... and this "cats.xhtml" xforms page:

<?xml version="1.0" encoding="UTF-8"?>
<html xmlns:xhtml="http://www.w3.org/1999/xhtml"
xmlns:xforms="http://www.w3.org/2002/xforms"
xmlns:xxforms="http://orbeon.org/oxf/xml/xforms"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:ev="http://www.w3.org/2001/xml-events"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:xi="http://www.w3.org/2001/XInclude">
<head>
        <title>CATS</title>
        <xforms:model id="main-model">
<!-- note: modify @src to point to above xml file -->
                <xforms:instance id="cats-instance" src="cats.xml"/>  
</xforms:model>
</head>
<body>
        <h1>--- Cats ---</h1>
        <ul>
                <xforms:repeat nodeset="instance( 'cats-instance' )/cat"
id="cats-repeat">
                        <xxforms:variable name="type" select="@color" />
                        <li>
                                <xforms:output value="$type" />
                        </li>
                </xforms:repeat>
        </ul>
</body>
</html>

... and this page flow:

<config xmlns="http://www.orbeon.com/oxf/controller"
xmlns:oxf="http://www.orbeon.com/oxf/processors"
xmlns:p="http://www.orbeon.com/oxf/pipeline"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" >
        <page id="cats001" path-info="/cats/" view="cats.xhtml"/>
        <epilogue url="oxf:/config/epilogue.xpl"/>
</config>

... I get the following error: 'Invalid element in XForms document:
xxforms:variable" when attempting to run this example. If the xxforms:variable
element is removed and "$type" replaced with "@color", the xforms page works
fine.

Could it be that you are using Orbeon Forms 3.6? <xxforms:variable>
was introduced after the 3.6 release, and you will need to use a
nightly build to use <xxforms:variable>. You can download the war of a
nightly build from:

http://forge.objectweb.org/nightlybuilds/ops/ops/

Yes, I was running 3.6 and 3.7 solves the problem!  Thanks!
