Newly rendered DOM elements not sortable

[kjanoudi]

When new items are added or a set of items is replaced via new props, those new items/replaced items have not had Sortable.create called on them, and therefore their DOM elements are not sortable.

This is due to having the Sortable.create call only in componentDidMount but not also in componentDidUpdate

How about calling this.setState within componentWillReceiveProps?

@Sortable(options)
class SortableList extends React.Component {
    state = {
        items: this.props.items
    };
    componentWillReceiveProps(nextProps) {
        this.setState({ items: nextProps.items });
    }
    render() {
        :   :   :
    }
}

I can get it work with this example, and here is a demo.

@cheton that works if the render function always returns a list. However, in the event that the list of items is empty, in my use case, i am returning a message that says "This list has no items", and the render function never gets to the portion where a list is rendered. Perhaps this is a design flaw on my end by not extracting the sortable portion into it's own component?

Flipping back and forth between lists that have no items and lists that have some items results in sortable not working

render() {
        const { items } = this.state
        if (!items || !items.length) {
            return <p>There are no items in this category.</p>
        }

        return (
            <div>
                <ul ref="list" >
                    {items.map((i, k) =>
                        <li key={k} >
        ....
       )

I just realised what you have encountered. I will take a look at your PR and merge it soon. Thanks!
