Desktop / Enlightenment / Elementary - woochan lee [samsung.com] - 9 November 2015 18:28 UTC

Summary: When spinner activated with entry, user can input any characters in entry. It degrades the usability.

I will add entry filter for limit size as well after this commit. This spinner features may help for app developer and users too.
