[gregberge]

Creating a new instance of error triggers two additional rendering when typing in an input, using same instance prevent it to happen.

@christianalfoni do you intend to merge it? Also can you make a release after? Thanks 👍

@neoziro Hi! Could you add a test for this case?

[gregberge]

@Semigradsky for multiple rendering I don't see how to write the test :/

[Semigradsky]

@neoziro ok, could you show this in http://codepen.io/semigradsky/pen/dYYpwv?editors=001 ? Just fork this pen and edit it.

[gregberge]

@Semigradsky you can see 3 render in the console http://codepen.io/anon/pen/EVpEpd?editors=001
With my modification, you will see only one.

[Semigradsky]

Nice! I added test 59bde83 and merged it

[gregberge]

@Semigradsky thanks, can you release it?

[Semigradsky]

Nope. @christianalfoni ?

@christianalfoni: could you transfer the ownership of this project if you're not maintaining it anymore.
