I was curious if there was a clean way to remove particular selections from a Featurelayer.I tried a couple of different methods to limit the selection to first selected feature.I thought I could cheat and splice the selectedFeaturesvar x:uint = featurelayer.selectedFeatures.length;
featurelayerselectedFeatures.splice(1,x);
But that didn't work.Then I tried to grab the first graphic and make a new FeatureCollectionvar g:Graphic = featurelayer.selectedFeatures[0];
featureLayer.featureCollection = new FeatureCollection(new FeatureSet());
That didn't work either.The next step I suppose would be to use the first graphic geometry to do second selection query on the FeatureLayer, but that seems a bit heavy handed.The reason I am using FeatureLayer is that this is for a custom component and it is much simpler to pass a FeatureLayer with built in query/selection capabilities than to pass a QueryTask URL and an existing GraphicsLayer on the Map, plus it fits into my workflow as I have some listeners in the main app for when a selection ends on the FeatureLayer being passed.If there's no way to tweak the SelectedFeatures after the fact, I'll just go the QueryTask/GraphicsLayer route, but I figure it couldn't hurt to ask.
