----------------------------------------

I can reproduce it again.
But this issue with NPE is a bug of Eclipse WTP:

So this is an upstream issue.

Second thing is that after this facet settings (for second attempt is that ok) doesn't work Seam validation for components.xml, which should work.

The project has /resourses folder as web root folder. But when you're adding Web Modul facet to the project you left default WebContent folder as a root. So you got a new web root folder but components.xml is still in resources which is not a root folder.
You have to configure the root folder in Web Module facet install dialog.
If you want to use multiple roots then you may face another problem with validation. Seam tools doesn't support multiple web roots. See JBIDE-12410
