Synthetic event warning on React15.0.1

[hafen]

When adding event handlers to numeric input components in React 15.0.1, I get the following warning in the javascript console:

Warning: This synthetic event is reused for performance reasons. If you're seeing this, you're accessing the property type on a released/nullified synthetic event. This is set to null. If you must keep the original synthetic event around, use event.persist(). See https://fb.me/react-event-pooling for more information.

Same problem. React 15.0.1.
Simple usage:

<NumericInput min={0} max={100} value={50}/>

Generates warning.

There is new release (2.0.4) and the component is now compatible with React 15.
