`keepOpenState={true}` no effect about react-native-nested-listview

@mofengfs Do you have an example I could work on? Here in this example you can find that changing the data keeps the state of the nodes opened (obviously if the data is completely new is going to start from being close) https://github.com/fjmorant/react-native-nested-listview-examples/blob/master/DynamicContentExample.js

Hi,

i am also facing the same issue. Cant able to open all child nodes initially. anybody can suggest a solution for it. I listed my code below.

<NestedListView data={vehicledata}
getChildrenName={(item) => 'fleets'}
onNodePressed={category => {}}
keepOpenedState={true}
renderNode={(fleet, level) => {
return (

<View
style={[
Interfacestyle.fleetgroup,
{
backgroundColor: colorLevels[(level-1)] ,
paddingLeft: ((level-1) + 1) * 1,
},
level==2 && searchinput.length>0?{marginBottom:5}:null
]}>

                        <CheckBox 
                            containerStyle={Interfacestyle.fleetcheckbox} 
                            checked={level==1?fleetdata.group[fleet.GroupId]:level==2? (fleet.GroupId in fleetdata.stations )=== false?false:fleetdata.stations[fleet.GroupId][fleet.StationId]:(fleet.StationId in fleetdata.fleets=== false)?false:fleetdata.fleets[fleet.StationId][fleet.fleetId]} 
                            size={19} 
                            onPress={() => { level==1?selectfleet(fleet.GroupId):level==2?selectfleet(fleet.GroupId, fleet.StationId):selectfleet(fleet.GroupId, fleet.StationId,fleet.fleetId)}} 
                            style={Interfacestyle.checkbox} /> 
                        <Text style={Interfacestyle.fleetgrouptext}>{fleet.name}</Text>
                                      
                      </View>
                  </NestedRow>);
            }}>

            </NestedListView>

i listed the array below.

vehicledata=[
{
"GroupId":1,
"name":"Test1"
"fleets":
[
{

"GroupId":1,
"subgrpoup":1,
"name":"test1.1"
"fleets":
[
{
"name":"test1.1.1"
"subgrpoup":1.1.1,
"GroupId":1,
"id":1
}
],
}
],
}
]

This is fixed in the latest version of the library, take into account that if you change completely the data of the list with new one then this library starts the state from the beginning because you've never opened those new nodes
