MapView is unable to load FeatureLayers with the error message, "Tried to get a LayerCollisionInfo for an index that doesn't exist!" when more than one layer has a LabelClass visible on loading.

解决办法

• Load MapView with only one of the labeled layers visible, then set up a watch on the 'updating' property of the FeatureLayerView. Once the layer is finished updating, display the next labeled layer.
• See Sample here.
