can somebody explain how to register a new node in my extension?
I figured out that an additional vue-component is needed that will set the node.link-property.
This must be registered here in the index.php of the extension:
If not doing this, you can't save new page of type of the new node in the Admin-Area.
The exception tells that node.link must be set.
For what is this link standing for? Where is it used? I did not found anything about that in the docs.
