I have a map and a layergroup.

var map = L.map('map').setView([27.6758,85.3313], 12);
L.tileLayer('http://{s}.tile.cloudmade.com/8ae544230be74379927e6dee5d416398/997/256/{z}/{x}/{y}.png', {}).addTo(map);

layergroup = new L.featureGroup();

js_arr = [[27.675765991210938,85.33130645751953],[27.675764083862305,85.33131408691406],[27.675764083862305,85.33131408691406],[27.675764083862305,85.33131408691406]]; 

layer.boundary_geom = L.polygon(js_arr);



After the map is displayed i have a button which calls map.setView(....). The problem is that if fitbounds is commented out setview works, if fitbounds is active then setview doesnot work.


You have several mistakes in your code:

  • You are using a factory method as a constructor. Instead of var foo = new L.featureGroup(), use var foo = L.featureGroup() or var foo = new L.FeatureGroup(). Note lowercase/uppercase! Leaflet coding style favours using factory methods (lowercase, no new).

  • layer is not defined, so you cannot assign layer.boundary_geom.

  • Your polygon coordinates have repeated coordinates. In practice this means that your polygon only has two vertices.

  • The polygon coordinates are very close, only a few meters apart. When fitting to bounds, the map will hit maxZoom, and your polygon will appear to be just one point.

Once these are taken care of, a demo map looks just fine, in both Leaflet 0.7.x and 1.0.0-beta.


This was problem of leaflet crashing when it had to draw many features. i called the map.fitbounds after 1 sec and it worked.
