Hi,
For the override, you have to check that you are editing the view for the right (front-end & back-end) template.
By removing the lines from the view, it remove the display of the product code, there is no other way for the view to display it.
But you have to be sure to edit the right view for the right context.
About the other post ; the name of the thread does not help because it talked about several issues in the same time.
