Snapping with SketchViewModel for JimuLayerView Layer

Hi all & @RobertScheitlin__GISP @JeffreyThompson2 ,

I was trying to apply snapping functionality in the SketchViewModel using experience builder custom widget. Here is the code I was using.

this.sketchViewModel=new SketchViewModel({
view:this.state.jimuMapView.view,
layer:this.GraphicsLayer,
pointSymbol: jsonUtils.fromJSON(defaultSnapSymbol) as any,
})
this.sketchViewModel.snappingOptions= {
enabled: true, // global snapping is turned on
selfEnabled: true,
featureEnabled: true,
featureSources: this.getDefaultSnapSources(this.state.jimuMapView,["dataSource_1-name_6192-48"])
}
getDefaultSnapSources = (jimuMapView: JimuMapView, defaultSnapLayers) => {
if (!jimuMapView) return []
//await jimuMapView.whenAllJimuLayerViewLoaded()
if (!jimuMapView?.jimuLayerViews) return []
   const allViewLayerKeys = Object.keys(jimuMapView.jimuLayerViews)
   const snapLayersSources = allViewLayerKeys.filter(layerViewId => {
   return       defaultSnapLayers?.includes(jimuMapView.jimuLayerViews[layerViewId].layerDataSourceId)
}).map(lvId => {
return {
   layer: jimuMapView.jimuLayerViews[lvId].layer,
   enabled: true
   }
})
return snapLayersSources
}

Thanks

Srikanth

Code seems good.

Error messages and snapshots will help.

Thanks for responding.

I identified the root cause of the issue: JimuLayerView should not be used, and snapping is only supported on FeatureLayer, GraphicsLayer, and a few others. To resolve this, I created a new FeatureLayer and added it to the map.
