I'm using a LayerList to manage layers in the associated map, but none of the sublayers show up in the LayerList widget. The LayerList does not have it's view property set, as I found this allowed me to manually manage the operationalItems.
My intention is to maintain a list of the available layers but only create and add the layers to the map when they're needed. So, the layers are created as follows (typescript):
let newItem = new ListItem();
newItem.layer = new MapImageLayer({
url: item.url,
id: item.id,
title: item.title,
listMode: 'show',
visible: false
})
newItem.title = item.title;
newItem.layer.watch("visible", this.toggleLayer);
itemArray.push(newItem);
itemArray is then used to create the LayerList operationalItems, and the toggleLayer method essentially adds the layer to the map, if it wasn't already.
Thanks.
