Changing Graphic Geometry (Moving Graphic) 4.x

GabrielLittman — Tue, 24 Jan 2017 02:47:45 GMT

Hi All,

I'm am trying to create a FeatureLayer that updates in real time in the ArcGIS API for JavaScript in 4.x. I seem to be able to update my graphic object (change the geometry) and it looks right when I print it out the console. But the graphic doesn't seem to move on the map. The only way I seem to be able to get it to move is to remove it from the layer and add a new graphic. Am I missing something? Is what I'm trying to do possible?

Gabriel,

According to the 4.x functionality matrix:

Functionality matrix | ArcGIS API for JavaScript 4.2

Modify graphics

Coming soon

To modify a graphic that is already added to the layer: you need to clone it, make modifications, add it to the layer and remove the original graphic. In-place modification of graphic objects will not trigger display refresh.

I just wrote about this.

Quick Tip - Clone in ArcGIS JSAPI - odoenet

Here is a demo app

JS Bin - Collaborative JavaScript Debugging

It's not real editing, but can be useful.
