This is the problem.
The items variable is a JavaScript wrapper for the Node interface. As
such it is not an array and does not have a length property.
If you want to iterate over the child nodes of items, the best thing is
to call the getNodes() method like this:
<%
var items = currentNode.lineItems.getNodes();
for (var i=0; i < items.length; i++) {
%><%= items[i].itemDescr %><%
}
%>
The items object here is actually a normal Object where the contained
nodes can also be accessed by name (unless as in your example, the node
names are numbers....).
Hope this helps.
