Hello @VasconcelosAqui , did you fix this? I'm having the same problem.
I think it's related to those annotations. But I wasn't able to make it
work. Even this line doesn't work because current resource is in the
template and the resultant currentPage will be structure of that
Have you fixed the null Teaser object in your test when you did adaptTo?
I'm trying to do the same with an extesion of the Image core component
but I'm still having my image field (the one with the @Self) null.
