    Setting a location field in an infotable

    Hello there !

    I've got a little problem here, I'm trying to get some network connections with the location field of the Things added in, but when I do this :


    for (var x = 0; x < tableLength; x++) {

        var row = result.rows[x];

        row.location = Things[row.to].geolocalisation;



    I only get some NaN in the field;

    I can still retrieve the field correctly when I add it in a new row (i'll probably just do this but I still wanted to ask).


    Thanks for reading

        There are a few ways this snippet could fail.


        1. Are tableLength and result.rows the same length?

        2. Is row.to a valid ThingName that exists?


        You should add some logger.info(""); lines and look in your scripting log in Monitoring>Script to make sure these values are valid. NaN stands for Not A Number which is usually the result of an impossible calculation. Variables that fail to get assigned would would have the value, "undefined". Can you post the entire service?

            Yeah, everything is looking good until i'm trying to put the location value in the location field

            as you'll see, row.to is a valid thingName since i'm getting it directly from the network  and the length are effectively one and the same

            and the geolocalisation field is a valid and legit one


            Here's the whole service (new working version) :


            var params = {

                maxDepth: depth /* NUMBER */,

                start: start /* STRING */


            var nw = start ? Networks[network].GetSubNetworkConnectionsWithTemplate(params) : Networks[network].GetNetworkConnectionsWithTemplate(params);


            var params = {

                infoTableName : "InfoTable",

                dataShapeName : "NetworkConnectionWithData"


            var result = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape(params);


            var tableLength = nw.rows.length;

            for (var x = 0; x < tableLength; x++) {

                var row = nw.rows[x];

                var newEntry = new Object();

                newEntry.from = row.from; // STRING - isPrimaryKey = true

                // row.location =  Things[row.to].geolocalisation <-- This is what doesn't work

                newEntry.location = Things[row.to].geolocalisation; // LOCATION

                newEntry.avatar = Things[row.to].GetAvatarURL(); // IMAGELINK

                newEntry.thingTemplate = Things[row.to].thingTemplate; // THINGTEMPLATENAME

                newEntry.to = row.to; // STRING - isPrimaryKey = true

                newEntry.connectionType = row.connectionType; // STRING

                var dN = Things[row.to].displayName;

                newEntry.display = dN ? dN : row.to;

                newEntry.alert = Things[row.to].alert ? Things[row.to].alert : false;
