Feature Layer. Disappearing points.

If “Apply Edits” method used on second Feature Layer, then after pausing and resuming the application, features load, but don’t appear.

Hi,

I had a similar issue with flex ....

when the edits where applied, the graphics disappeared ..

and had to create a new instance off the graphic that wasnt connected to the graphic layer and it kept the graphics on the screen in this function below ...... (instead of using the graphic input from the function)

hope this helps ..

private function FeatureOperation(graphic:Graphic, shapetype:String, operation:String):void
			{
				
				if(operation == "add")
				{
					
				
				///test applying edits
				const attr:Object = {};
				
				var date:Date = new Date();
				
				//set attributes
				attr["BlastID"] = blastID.text;
				attr["DateCreated"] = date.time;     //1227663551096;
				attr["StartDate"] =  null;   ///1227663551096;
				attr["StartTime"] =  null;   ///1227663551096;
				attr["FinishDate"] = null;
				attr["FinishTime"] = null;
				attr["CreatedBy"] = null;
				attr["InnerBuffer"] = innerBuffer.text;
				attr["OuterBuffer"] = outerBuffer.text;
				attr["ShapeType"] = shapetype; 
				attr["Status"] = 1 ; ///Domain: Coded Values: [1: Active], [2: Inactive], [3: Planned], ...1 more...)
				
				var g:Graphic = new Graphic(graphic.geometry,null,attr);
							
				///graphic.attributes = attr;
				
				
				FeatureLayer(editfs).applyEdits( [ g ], null, null , true, new AsyncResponder(featureLayer_editsCompleteHandler, featureLayer_faultHandler));
				
				};
