Hi all, i am trying to get the Preview function to work inthe Umbraco BackOffice. I am currently using umbraco 4.0.4.2 and was hoping someone could comment on what i am trying to do.

Bascially the preview function works for <umbraco:Item 's in the template files. In my XSLT and user controls it doesnt. I have created a variable and set its value to either a copy of the currentPage or it goes off to a custom xslt extension

<xsl:variable name="versionedPageRaw">
    <xsl:choose>
        <xsl:when test="string-length($umbVersion) != 0">
            <xsl:copy-of select="WebFunctions:getVersionedPage($currentPage/@id)"/>
        </xsl:when>
        <xsl:otherwise>
            <xsl:copy-of select="$currentPage"/>
        </xsl:otherwise>
    </xsl:choose>
</xsl:variable>
<xsl:variable name="versionedPage" select="msxml:node-set($versionedPageRaw)/node" />

My getVersionedPage function is below and was hoping someone could let me know if there is anything wrong with what i am doing.

        public static XPathNodeIterator getVersionedPage ( int rootNodeId )
        {

            XmlDocument xmlDoc = new XmlDocument ( );
            XmlElement rootXmlNode = xmlDoc.CreateElement ( "node" );

            xmlDoc.AppendChild ( getNodeRecursively ( rootNodeId, rootXmlNode, ref xmlDoc ) );

            XPathNodeIterator myIterator = null;

            myIterator = xmlDoc.CreateNavigator ( ).Select ( "/" );

            return myIterator;

        }

            try

                    elemXmlNode.SetAttribute ( "parentID", document.Parent.Id.ToString ( ) );
            }
            catch ( Exception ex )
            {
                elemXmlNode.SetAttribute ( "parentID", "-1" );
            }
