Base setup:
Adding a template definition, which extends another template definition (see print screen).

Problem:
If the value of the extends property is set wrong, all template definitions registered below the wrong node are invalid.
So if placed for example below the stkSection (see print screen), all template below are not found anymore (print screen).

Behavior on correct reconfiguration:
When correcting the wrong extends value, all templates are registered correct again.

What should be changed:
Following template definitions of a wrong definition should be still registered. and usable.
