Listview blanks when using navigator pop - react-native

Question

I am facing two problems & can not resolve this. Can anyone explain why this is happening? Or can anyone give me the solution?
Problem NO 1:
There are two components 1) Home 2) Inner
In the Home there are list of data & when I click any one of them it route to Inner. There are also a back button with using navigator pop. There is the issue sometime reproduce - When I click on back, it routes to Home but there is no data(listview element) but when I touch on the screen the data shows properly.
Problem NO 2:
In the home component within the list data, there also some repeated data within the single row.
I have used map function for this. Sometimes ( Most of the time it shows correctly ) it is also not shown in list view, the row is showing properly but the repeated data are missing.
<ListView onEndReached={this.props.reloadArticles} onEndReachedThreshold={10} dataSource={this.props.dataSource} renderRow={this.renderPost} enableEmptySections={true} refreshControl={ <RefreshControl refreshing={this.props.isRefreshing} onRefresh={this.props._onRefresh} /> } />

Answer 1

NO 1:
Sounds like this: https://github.com/facebook/react-native/issues/8607
If you use rn 0.4.0 setting initialListSize={0} could help
NO 2:
Could you please post your renderRow / dataSource code

#SnowMax Sorry for late reply & thanks for help.
Due to confedential project I could not share all code but I can share u the code structure:
renderPost = (list, sectionID, rowID) => {
if(list && list.is_shared_post == true){
return (
<WallShared list={list} rowID={rowID} />
);
}
}
class WallShared extends Component {
constructor(props) {
super(props);
}
render() {
if( this.props.list.is_shared_post == true){
switch(this.props.list.TblPostsComments.post_type){
case 'T':
return (<ShareText list={this.props.list} />);
default:
return (<ShareDefault list={this.props.list} rowID={this.props.rowID} />);
break;
}
} else {
return (
<View>something</View>
)
}
}
}
export default WallShared;
class ShareText extends Component {
constructor(props) {
super(props);
this.state ={
isLoggedIn:false,
}
}
componentDidMount(){
}
render() {
var ShareBlock = this.props.list.TblPostsComments.shared_contents.map(function(cont, ind) {
return (
<View style={[styles.feedItem, styles.SfeedItem]} key={ind}> </View>
);
},this);
return(
<View style={styles.feedItem}>
<View style={styles.sharedWrap}>
{ ShareBlock }
</View>
</View>
);
}
}
export default ShareText;
