I am trying to render a page, accessing the child elements in a schema. I have looked throught the freemarker documentation but just don't see the forest for the trees.

If someone can take a look at the following and point me in the right direction I would appreciate it. Thanks

I keep getting the following error:
error regenerating rendition using company_superseminars.ftl: freemarker.core.NonStringException: Error on line 58, column 21 in freemarker_template Expecting a string, date or number here, Expression slist.locationNew is instead a freemarker.ext.dom.NodeListModel

Here is the schema:


<?xml version="1.0"?>
<xs:schema xmlns:alf="http://www.alfresco.org"
 xmlns:xs="http://www.w3.org/2001/XMLSchema"
      xmlns:avss="http://www.company.com/avss"

           elementFormDefault="qualified">

</xs:schema>

And here is the freemarker giving the error:


<#ftl ns_prefixes={"avss":"http://www.company.com/avss"}>
<#assign company_superseminars = .vars["avss:company_superseminars"]>

<html>
<body>
<#list company_superseminars["avss:seminarLocation"] as slist>              
<br>         ${slist.locationNew}
</#list>
</body>
</html
‍‍‍‍‍‍‍‍‍‍‍‍

OK after more research, this returns the element children as long as there is only 1 child set. If there are more than 1 it blows up with:

error regenerating rendition using company_superseminars.ftl: freemarker.template.TemplateException: Expected node model. company_superseminars["avss:seminarLocation"] evaluated instead to freemarker.ext.dom.NodeListModel on line 56, column 22 in freemarker_template.

<#assign seq = company_superseminars["avss:seminarLocation"]/>
              <#list seq?children as c>

                 ${c}

              </#list>

Any ideas?

Thanks to ddekany over at the freemarker forum, <#list seq.* as c> is what works in case anyone else has trouble.
