Passing a FeatureSet with Attributes to a Geoprocessor

[DeonaEvans]

How do you set up the FeatureSet to pass as an input parameter to a geoprocessing function and pass the attributes as well?  Given a graphic:Graphic, I need to pass it as an input.  The model for the geoprocessing tool was built with the same feature class (schema) as the graphic I'm trying to input.  I get a "Failed" on the status messages when I run the geoprocessor.

var featureSet:FeatureSet = new FeatureSet();
var features:Array = new Array();
var geom:Geometry = graphic.geometry;
var attrs:Object = graphic.attributes;
var obj:Object = {geometry:geom, attributes:attrs};
features.push(obj);
featureSet.features = features;

I tried this another way.....

var featureSet:FeatureSet = new FeatureSet();
featureSet.features = new Array();
featureSet.features.push(graphic);
featureSet.spatialReference = map.extent.spatialReference;

This didn't work either. My gp tool only has one input parameter as show here:

[INDENT]Parameter: Feature_Class

Data Type: GPFeatureRecordSetLayer

Shape_Area (Type: esriFieldTypeDouble, Alias: Shape_Area)
Parameter Type: esriGPParameterTypeRequired[/INDENT]

When I don't send the attributes with the graphic, then it works. Otherwise it does not. What am I doing wrong?

I figured out what the problem was.  The input featureclass was expecting an FID (instead of OBJECTID) for the OID field.  The featureclass I was sending didn't have this.  The reason the FID entered the picture in the first place was I exported that layer using ArcMap and FID was introduced that that point.  I didn't even notice it.  So when I created the GP model and pointed to that featureclass (exported with FID) for the schema for the input parameter, FID was expected.
