API 4.9, LayerList + TileLayer bug?

DavideLimosani — Tue, 04 Dec 2018 13:57:42 GMT

Hello everyone,

give a look at this sample:

It just adds a Tile layer to a LayerList widget (with api 4.8) and everything looks fine.

If you switch to 4.9 (API 4.9) you can see a totally different behaviour. It looks like that the tile layer becomes a group layer and every single sub layer is added as a layer. I don't think this is the intended behaviour.

Is it a bug?

Thanks,

Davide

Hi there,

It is an expected behavior at 4.9. TileLayer.sublayers property was added at 4.9. So you have to set the TileLayer.listMode to hide-children to not show the sublayers information as shown below:

var layer = new TileLayer({
  url: "https://sit5.sistemigis.it/sit/rest/services/Demo/DemoCache/MapServer",
  title: "Tile layer",
  listMode: "hide-children"
});

Hey Davide Limosani, there actually is a bug here but the workaround Undral Batsukh provided is a good one! thanks for letting us know about the issue.
