Leaflet: Cannot read property '_leaflet_id' of undefined

Created on 17 Oct 2012 · 4Comments · Source: Leaflet/Leaflet

Some time when refreshing the page I am getting this error in chrome:

Uncaught TypeError: Cannot read property '_leaflet_id' of undefined leaflet.js:6
(anonymous function) leaflet.js:6
n.Map.n.Class.extend.hasLayer leaflet.js:6
domController.map.manageZoom domController.leaflet.js:647
n.Mixin.Events.fireEvent leaflet.js:6
n.Map.n.Class.extend._resetView leaflet.js:6
n.Map.include.n.DomUtil.TRANSITION._onZoomTransitionEnd leaflet.js:6
n.Map.include.n.DomUtil.TRANSITION._catchTransitionEnd leaflet.js:6
e.(anonymous function).u

this happen when:

if (!map.hasLayer(tilelayer)) {}

Any idea why this is happening and how to solve it?
When this happens the map gets unusable until refresh.

This happens when tilelayer variable is undefined at the moment when this line executes. Put a debugger statement there and figure it out, shouldn't be hard.
