There is no usable way to create and populate a new node within a content app.

In v5 we offered the action "OpenCreateDialogAction" which opened a dialog which, when saved, would create a new node and populate it.

This can still be seen in Magnolia 6 in the Security app. When creating a new user, the dialog is opened and no node is created until clicking submitting the form.

Similar behaviour can be created with a chained action but this creates an untitled node and then opens the dialog. Dismissing the dialog leaves behind an unpopulated, untitled node.

The CreatePageAction class from magnolia-pages-app solves this problem with hardcoded references to nodetype and the use of the registries to find the dialog.
