thanks for response but my task is still open.
With the Template am able to define some default stuff for the creation dialog. But I’m not able to find a solution where I can set an defaultValue for the titel of the Node itself.
You can change the displayed title (in the structure tree) by changing the label in the NodeType Definition. The default is defined like this (i removed some parts for better readability):
If you want to set a default value for properties, you simply can set it that way:
'Your.Package:NodeType':
properties:
title:
type: 'string'
defaultValue: 'Your default value here'
If you want to use a default value in the creation dialog: I’m not sure if this works. Maybe @dimaip can tell you if that works.
If you want to set the default values of a child node, you need to use the package posted by @daniellienert or extend another nodetype and update the defaultValue.
