I created a map and added markers on it in salesforce lightning component , issue is: click on marker >> click on map (this close the popup) >> zoom in and out >> this error displayed for each zoom step:
Uncaught TypeError: Cannot read property '_latLngToNewLayerPoint' of null throws at /resource/1498411629000/leaflet/leaflet.js:9:10763
this is the code in component javascript helper:
({
drawMap: function(component,map){
var mapElement = component.find("map").getElement();
map = L.map(mapElement).setView([35.232, 40.5656], 12);
L.tileLayer('https://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer/tile/{z}/{y}/{x}',
{
attribution: 'Tiles © Esri'
}).addTo(map);
var markers = L.marker([35.232, 40.5656]).addTo(map);
component.set("v.map", map);
component.set("v.markers", markers);
},
putMarkers: function(component) {
var map = component.get('v.map');
var markers = component.get('v.markers');
var projects = component.get('v.projects');
var projectsAction = component.get("c.getProjectsList");
var markerArray = [];
var symbol;
var symbol1 = 'symbolURl';
var symbol2 = 'symbolURl';
projectsAction.setCallback(this, function(response) {
var state = response.getState();
if( state == "SUCCESS"){
projects = response.getReturnValue();
if (markers) {
markers.remove();
}
// Add Markers
if (map && projects && projects.length> 0) {
for (var i=0; i<projects.length; i++) {
var project = projects[i];
if (project.Latitude && project.Longitude) {
var latLng = [project.Latitude, project.Longitude];
var currentStatus = project.status;
if(currentStatus=="status1")
symbol = symbol1;
else if(currentStatus=="status2")
symbol = symbol2;
var popupTemplate = '<b style="color:black; font-size:11px;">Project Name:</b><span style="float:right;margin-right:10px;color:#800000;font-size:11px;width:110px;text-align:right; white-space:normal;" > '+project.name;
var icon = new L.DivIcon({
className:'',
html: '<img style="width:34px;height:37px;" src="'+symbol+'"/>'+
'<span style="font-weight:bold;font-size:9pt;">text</span>'
});
var marker = L.marker(latLng, {project: project,icon:icon,title:project.name}).bindPopup(popupTemplate,{minWidth:200});
markerArray.push(marker);
}
}
L.layerGroup(markerArray).addTo(map);
component.set("v.map", map);
}}
else if(state == "ERROR"){
console.log('Error in calling server side action');
}
});
$A.enqueueAction(projectsAction);
}
and in javascript controller:
jsLoaded: function(component, event, helper) {
var map = component.get("v.map");
if (!map) {
helper.drawMap(component,map);
helper.putMarkers(component);
}
},
projectsChangeHandler: function(component, event, helper) {
helper.putMarkers(component);
}
it seems this issue is only on salesforce where is the problem? please help
