I met the same problem, I want to use version 2.1.4, what should I do? |
|
Use 2.1.5+ versions and encapsule all the elements in additional parent like so: return h('div', {}, [h('label', 'Test123'), h('label', 'Test123')];Or just revert to 2.1.4 and wait to see what will happen with this Issue. |

The question has been decided.Thank you so much. |

I use functional component as the only way to get rid of extraneous root component |

Vue.js version
2.1.5, 2.1.6
Reproduction Link
[2.1.4] https://jsfiddle.net/uriziel01/kx1yuu3a/ [working]
[2.1.5] https://jsfiddle.net/uriziel01/kx1yuu3a/3/ [broken]
Steps to reproduce
Return array of elements from render function in functional component.
What is Expected?
Multiple root nodes seems to be dissallowed in Vue2 everywhere but not here.
I think that the correct solution would be to throw appropriate error to console and avoid returning
undefined. Or is that designed logic and this should be handled by the engine as it was in older versions? You decide.What is actually happening?
undefinedis rendered as a result and no correct error is thrown to the console.
