I tried this http://www.fredparke.com/blog/using-custom-template-files-different-display-modes-drupal-7, but doesn't work, gives errors and tried this How to provide template for particular view mode?How to provide template for particular view mode? kind of works, but gives errors.
My content type is product_display and view mode is Product List, created with display suite. I need this, so I could delete h2 title from it, because views forces title output via rendered entity format no matter what.
Errors I get are either Notice: Undefined index: product_display in mytheme_preprocess_node() (line 170 of /template.php).
