i have a document library with a customized grouping. In the view setting i enabled the column "Name (linked to document with edit menu) )". Problem is that the edit menu didn't show up. For testing purpose i made a secound view as a normal table view without any grouping and enabled the same columns. In this view the edit menu is visible and all works as expected. I tested this with an admin account so i don't think it's a security issue.
Some ideas would be great!
