Why won't my Table on Contents Widget Work?

I use a try...catch block to see if my TOC is having any issues. Are you getting errors in your console?

        try {
            var toc = new TOC({
                map: map,
                layerInfos: layerInfo
            }, "divLayers");
            toc.startup();

            toc.on("load", function () {
                console.log('TOC loaded');
            }
        }
        catch (e) { console.error(e.message); }

KenBuja — Sat, 11 Dec 2021 16:18:30 GMT

OK, I've made a few changes to your script. The biggest one was to change the event where the TOC was loaded. Originally, that was in the "layer-add-result" function, which is fired every time you add a layer. Thus the script was trying to initialize a TOC whenever a layer was added. So now the layers are added in the "map.addLayers" method rather than in the "map.addLayer".

However...I'm still getting some strange activity that I haven't figured out. The dynamic layer is getting added twice with the error

Here's the script so far. If i have time, I'll try to figure out what's going on with the operationalLayer. I commented out some things, like the proxy and geometry service.

Re: Why won't my Table on Contents Widget Work?

ChrisSergent — Wed, 10 Dec 2014 21:36:03 GMT

I receive a: Tried to register widget with id==tocDiv but that id is already registered

I removed the comments from the geometry declaration as well as the proxy and the TOC loads with the duplicate layers, but you can not turn them off on the map. If you refresh the map, the layers are removed from the TOC, and then you can remove the layer from the map.
