@Vincent-Bastos Well, now the pages are always persistent, they are not removed and created again. We noticed this just made loading tabs way slower, so we made them persistent. Your Angular controller will be only run once at the beginning of the app. That’s why we recommended to put the code in show event instead, since it will be run every time you activate the tab (just like before).
Using loadPage for this would just be a dirty patch, but if you are ok with that you can read the docs here.
