Vue.js version


Reproduction Link

working v2.1.4 - https://jsfiddle.net/7eje1znn/
not working v2.1.5 - https://jsfiddle.net/74zsdfv5/

Steps to reproduce

Just open fiddle with v2.1.5 and check the console.

What is Expected?

Well it should work without throwing exception since I don't see any breaking changes in this new release regarding render function.

What is actually happening?

It seems that Vue suddenly doesn't accept false value in array of children vnodes.. And if we change this line:

labelLeft && label

to labelLeft ? label : null

then everything works correctly. No Error.
