附加信息

This is documented at https://developers.arcgis.com/javascript/latest/api-reference/esri-layers-MapImageLayer.html#sublayers. Where it states, 'All sublayers are referenced in the order in which they are drawn in the view (bottom to top). They may be added, removed, or reordered using the Collection methods." In order to specify the sublayers in a certain order, please use the Collection reorder method.

解决办法

The issue is that when Supports Dynamic Layers is true, the LayerList widget will renders correctly, however, when Supports Dynamic Layers is false, in order to make two sublayer show correctly in the map, instantiate the layer id order in a descending order, if using an ascending order the sublayer does not render, and the request are different.
