I found a bug in the ion-refresher directive when used with ion-list. If you pull down to refresh, you can see the pull-down text but the updating text+icon disappear when there is an ion-list after the refresher. I removed the list and everything is visible in the ion-refresher.
I added the demo from the ionic github to Codepen : http://codepen.io/anon/pen/HvgjF
If you remove the ion-list, you’ll see it working fine. Tried this in emulator and on device as well (ios) and works nowhere. Couldn’t find a way to fix it unfortunately. Anybody else have better luck?
