I'm probably just missing something, the editor policy I have created works as intended except for the mentioned problem: I can't create resources.
Editing, undeleting, deleting, moving, unpublishing and publishing works.
Edit: I just found out that the preview images in my TV's are not visible, while they are on the frontend. I've set basePath and baseUrl both to "uploads/".
assets and uploads both are in the same directory: "modx/assets", "modx/uploads".
The TV's contain "uploads/img/image.jpg".
It seems that modx now tries to display the images with "uploads/uploads/img/image.jpg".
