Thank you very much for pointing me to your native-app example.
After having a look into that I was able to fix my test application.

Hi,
I only glanced at your work and I see you're not using any toolkit. A
while back I've toyed a bit doing the same, this is what I come with
[1]. I 'adapted' the SHM client example from weston, into creating
multiple window/surfaces. I haven't tried in a while but should work.
I think it would be pretty nice to have something similar in AGL
repository, as a alternative to homescreen, but a bit more evolved so it
needs some clear polish (create other types of buffers, use EGL/GL), and
most like need to create some kind of toolkit library to handle drawing
some basic widgets and handle input. Without handling input you won't
be able to switch between other applications. It is quite a bit of work.
Might also take a look at different toolkits as inspiration to see how
they handle wayland part. Probably QtWayland is quite big to follow, but
maybe there are there some more slimmer choices. Besides that, there's a nice
book/how-to around wayland at [2], which you might find useful.
