just found this one today and wanted to share if anyone has this in order to post in Bug Tracker.
I tried to set a new cart promotion in v434 where as condition I have a specific brand. So I choose Product Featrures as Condition, then Brand as the Feature and then wait for it to show me all brands as dropdown list in order for me to choose the one I wish.
But this never happens. I just get an empty field as I should write manually the Brand myself.
This was tested in clean 433 installation (with demo content) and in the original CS-Cart 434 demo (demo.cs-cart.com). I got the same result in both cases.
If I choose another kind of feature for example Operating system then I get the dropdown list as it should happen. So I think the problem is in the type of the Feature (Brand/Manufacturer) which is the main change since version 306 where this fucntion works as it supposed to.
If anyone has this or can confirm this please doso ,and then we can open this in bugtracker.
