Error with modular pages after template switch

[marsien]

I have an error when I change the template of of modular page; for example, if i switch from "showcase" template to "about" template in antimatter. The error occur when I save the change, even if the change occurs.
After, i can not never open again this page in the admin plugin, I have always the same error.

Here, what Crikey says:
`Twig_Error_Runtime thrown with message "An exception has been thrown during the rendering of a template ("Undefined index: type") in "pages.html.twig" at line 246."

Everything works fine as long as the template selected when the modular was created is not changed.

What is "about", a modular child page type you created?

[marsien]

Yes, it is a template I created for modular child pages. I'm sorry,
I thought this template was in Antimatter theme. The problem is the
same with all other modular templates (in antimatter, ie: features,
showcase or text).

I think the problem occurs with template inheritance. Only modular files in both templates make this error.
