Cannot get node content using onCreateNode behavior

I've created a custom Java behavior bound to the onCreateNode event that works just fine, exceptthat I can't retrieve the content from the node using:ContentReader cReader = contentService.getReader(car.getChildRef(), nodeService.getType(car.getChildRef()));String content = cReader.getContentString(

It's been a while since you asked this but I see it hasn't been answered yet.

I had the same problem using a javascript behaviour. My solution was to use the onContentChanged behaviour instead. The signature is slightly different but it gets you access to the content and tells you if it's new content so you can simulate onCreateContent. Not a complete answer but hopefully it points you in the right direction.

Hi,

just as an idea: I had a similar problem (the onCreateNode methode was called, but requesting the properties of the new node doesn't get me all of the expected properties). As soon as I specified the NotificationFrequency to be TRANSACTION_COMMIT everything is working fine:


JavaBehaviour onCreateNodeBehaviour = new JavaBehaviour(this, "onCreateNode", NotificationFrequency.TRANSACTION_COMMIT);
policyComponent.bindClassBehaviour(OnCreateNodePolicy.QNAME, qNameOfMyType, onCreateNodeBehaviour);
‍‍‍‍

The reason seems to be, that the new node ist created (even with specialised type) which causes the event, and that later the additional properties are added. When you register to the onUpdateProperties event with default NotificationFrequency (= EVERY_EVENT) this event is raised twice. The first time the node contains only a few properties. The second time the others are present, too.
