FeatureLayer does not appear after initializing #57

Closed ynunokawa closed 8 years ago

I guessed at first that the position to run oldOnAdd in esri-leaflet-renderers is the cause of this issue. But lots of features in debug/sample.html (of esri-leaflet-renderers) draw with Leaflet's default marker symbol if fix it (see Esri/esri-leaflet-renderers#125).

It can be reproduced in L.esri.WebMap demo.

There are three points about this.

FeatureLayer does not appear (and send a query request)
Map controll will be unavailable if panning map before a layer appear
FeatureLayer appear after zooming map

FeatureLayer in L.esri.WebMap does not run onAdd in virtual-grid.js (leaflet-virtual-grid) when initializing it.

debug/sample.html (esri-leaflet-renderers)
index.html (L.esri.WebMap)

I guess that esri-leaflet-renderers imported into FeatureCollection of L.esri.WebMap overwrite onAdd of L.esri.FeatureLayer before reading esri-leaflet-renderers with <script>.
