I read the help about field-access-rights. (My karma is insufficient to publish links)
and thought it should work - but didn't.
I want to hide the product price to a specific user group. I just want to change the visibility to this one field. I don't want to change any python code or xml file. It worked in version 6.1 and in the link above it says it should also work in version 7.
So I opened the model for product in database structure and said edit... I clicked on the price field and I was able to add a user group for this price field. I saved the field (and it worked) but I still had to save the model but that doesn't work and the field change were undone. When I do this I get an error message saying: Properties of an elementary field can't be changed that way. Please do this by adapting your python code - ideally with your own modul.
Is it or is it not possible to change just a single fields visibility to a group... with no python code or xml changes...?
