I'm subscribing to the PublishingNotification with a class overriding INotificationHandler as is explained in the documentation.

I'm doing so because I need to create a row on my internal database for the node being published and then associate that new row primary key (id) back in the Umbraco node.

What happens is when I set the value of a node's property to anything different than it was, the node is saved with the new value in that property but the publishing is canceled. If I don't change the value the publishing happens as expected.

The property is of type "label (int)" and I'm using the following code:

var categoryNode = notification.PublishedEntities.FirstOrDefault(x => x.ContentType.Alias == "categoria");
categoryNode.SetValue("dbId", dbId);

Is this by design? If so, how can I force the publish to happen even if I change something?

Thanks!
