It looks like the XML feed does not have a namespace declared for the
'activity' prefix. The root 'wall' element should look something like this:
<wall xmlns:activity="http://www.someurl.com/something";>
This xmlns attribute is probably missing from your XML and so it cannot be
parsed correctly.
Note that if you need to use the data within <activity:object-type> for a role,
you'll need to declare the activity namespace using
XmlListModel::namespaceDeclarations. For example,
XmlListModel {
source: ...
query: "/wall/entry"
namespaceDeclarations: "declare namespace activity =
'http://www.someurl.com/something';"
XmlRole { name: "objectType"; query: "activity:object-type/string()" }
}
regards,
Bea
