Simple script called by behavior-context

I've got this script (onUpdateOrder.js) that works right in a rule's "Execute Script" action. The goal is to update a custom cm:folder property with the sum of its children property, when a custom type ("my:item") is updated in the context folder.var childrenList = space.children;if (childrenList){

Good time spent on Jeff Potts book (Alfresco Developer Guide). I worked on the User Rating Calculator and found the right solution:

This is the script used to recalculate Orders value (orders.js):

//calculate orders
function calculateOrders(childAssocRef) {
      var parentRef = childAssocRef.parent;
      
      // check the parent to make sure it has the right aspect
      if (parentRef.hasAspect("{http://www.alfresco.org/orders/content/1.0}orderAspect")) {
         // continue, this is what we want
      } else {
         logger.log("Item's parent ref did not have order aspect.");
         return;
      }
      
      // get the parent node's children
      var children = parentRef.children;

      // iterate through the children to compute the total
      var orderValue = 0;

      if (children != null && children.length > 0) {
         for (i in children) {
            var child = children[i];
            var itemPrice = child.properties["{http://www.alfresco.org/orders/content/1.0}itemPrice"];
            orderValue += itemPrice;
         }
      }         
   
      logger.log("Order result:" + orderValue);
      
      // store the value on the parent node
      parentRef.properties["{http://www.alfresco.org/orders/content/1.0}orderValue"] = orderValue;
      parentRef.save();
      
      logger.log("Property set");
      
      return;

}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

..and the controller (onUpdateItem.js) that calls the script to run against the current node:

<import resource="classpath:alfresco/extension/scripts/orders.js">
var scriptFailed = false;

//Have a look at the behaviour object that should have been passed
if (behaviour == null) {
 logger.log("The behaviour object has not been set.");
 scriptFailed = true;
}

//Check the name of the behaviour
if (behaviour.name == null && behaviour.name != "onUpdateNode") {
 logger.log("The behaviour name has not been set correctly.");
 scriptFailed = true;
} else {
 logger.log("Behaviour name: " + behaviour.name);
}

//Check the arguments
if (behaviour.args == null) {
 logger.log("The args have not been set.");
 scriptFailed = true;
} else {
 if (behaviour.args.length == 1) {
     var childAssoc = behaviour.args[0];
     calculateOrders(childAssoc);
 } else {
     logger.log("The number of arguments is incorrect.");
     scriptFailed = true;
 }
}

Deployed and tested, it works as well.
