I have some code to run through a list of order lines and send emails using the following XSLT file:

<xsl:param name="orderLine" />

  <xsl:template match="/">

    <h2>
      Your subscription renewal date is approaching. <xsl:value-of select="$orderLine/@id"/>
    </h2>    
    <table cellspacing="0" cellpadding="0" border="0" width="50%" style="margin-top: 15px;">
      <tr>
        <td>
          Subscription
        </td>
        <td>
          Username
        </td>
        <td>
          Activation Key
        </td>
        <td>
          Expiry Date
        </td>
      </tr>
      <tr>
        <td>
          <xsl:value-of select="$orderLine/properties/productName"/>
        </td>
        <td>
          <xsl:value-of select="$orderLine/properties/memberUsername"/>
        </td>
        <td>
          <xsl:value-of select="$orderLine/properties/activationKey"/>
        </td>
        <td>
          <xsl:value-of select="$orderLine/properties/expiryDate"/>
        </td>
      </tr>
    </table>

  </xsl:template>

The following code works fine, using the GetXML method to get the XPathNodeIterator, the bodyText variable is
populated with the details for each order line:

XPathNodeIterator orders = TeaCommerce.Library.GetFinalizedOrdersXml().Current.Select("order");
TeaCommerce.Data.Order order = TeaCommerce.Razor.TeaCommerce.GetOrder(Convert.ToInt32(orders.Current.GetAttribute("id", "")));
var subscriptions = from ol in order.OrderLines select ol;

foreach (OrderLine subscriptionOrderLine in subscriptions)
{
int orderUmbracoLanguageID = Convert.ToInt32(orders.Current.GetAttribute("umbracoLanguageId", ""));

XPathNodeIterator orderLines = orders.Current.Select("orderLine");

while (orderLines.MoveNext())
{
 Dictionary<string, XPathNodeIterator> parameters = new Dictionary<string, XPathNodeIterator>();
 parameters.Add("orderLine", subscriptionOrderLine.GetXml());
 string bodyText = XSLTHelper.InvokeXSLT("subscription_reminder_email.xslt", null, orderUmbracoLanguageID, parameters, false);

 <code to send email ...>
}

This code is a little more efficient as it is not calling GetOrder however it does not work.
The bodyText variable gets set but is missing the order line property values for all but one order line.

int orderUmbracoLanguageID = Convert.ToInt32(orders.Current.GetAttribute("umbracoLanguageId", ""));
XPathNodeIterator orderLines = orders.Current.Select("orderLine");
while (orderLines.MoveNext())
{
  Dictionary<string, XPathNodeIterator> parameters = new Dictionary<string, XPathNodeIterator>();
  parameters.Add("orderLine", orderLines);
  string bodyText = XSLTHelper.InvokeXSLT("subscription_reminder_email.xslt", null, orderUmbracoLanguageID, parameters, false);

<code to send email ...>
}

It's weird to me...what am I doing wrong? Is there a bug in XSLTHelper.InvokeXSLT?
