List View is not renderring

[saravanannnallasamy]

I have used the Basic Usage timeline list view in my ract-native page. It worked for its default data.
But when i include data via componentWillMount()

componentWillMount(){
    var list = CustomerStore.usagelist;
    this.setState({data:list});
    console.log(JSON.stringify(list));
}

the log is printing the data before runnning the render() but the listview is not showing
instead it throws a warning

Warning: In next release empty section headers will be rendered. In this release you can use 'enableEmptySections' flag to render empty section headers.

I have also used the flag, but there is no use.
<Timeline data={this.state.data} enableEmptySections={true} />
anybody have a solution for this...
I am using React-Native :0.38

I have resolved it by add the refreshing available in Pull to refresh and load more type of list view.
