Hi Jennifer – thanks for your reply.
I did some further debugging, and I don’t think it is related to the renderer. In all cases during the load, the layers come in showing a simple renderer, but with an empty symbology. This is true both of layers that display (secondary_ug_segment and junction_box) and layers that do not (transformer_oh_bank) in the examples from the immediate window pasted below. I don’t know what renderer would be getting applied, since all these are empty, but they all definitely have symbology in the APRX project that generates the geodatabase.
fl.Name
"secondary_oh_segment"
((ArcGISFeatureTable)fl.FeatureTable).LayerInfo?.DrawingInfo?.Renderer?.ToJson()
"{\"symbol\":{},\"type\":\"simple\"}"
fl.Name
"transformer_oh_bank"
((ArcGISFeatureTable)fl.FeatureTable).LayerInfo?.DrawingInfo?.Renderer?.ToJson()
"{\"symbol\":{},\"type\":\"simple\"}"
fl.Name
"junction_box"
((ArcGISFeatureTable)fl.FeatureTable).LayerInfo?.DrawingInfo?.Renderer?.ToJson()
"{\"symbol\":{},\"type\":\"simple\"}"
