Why is Editor.Change.Graphic null when Editorwidget saves?

[KirkKuykendall]

I've got a featurelayer with a definition query set up where Expiration_date is null.

When someone saves a feature with a non-null expiration date, I'd like for the graphic to disappear.

In the EditCompleted eventhandler however, the graphic is null.  Is this a bug?

private void OnSaveFeatures(Editor.EditEventArgs e)
{
    FeatureLayer fLayer = null;
    foreach (Editor.Change c in e.Edits)
    {
        if (c.Layer.ID.ToUpper() == "ProjectPolys".ToUpper())
        {
            fLayer = c.Layer as FeatureLayer;
            if (c.Graphic != null)
            {
                if (c.Graphic.Attributes.ContainsKey("Expiration_Date"))
                {
                    if (c.Graphic.Attributes["Expiration_Date"] != null)
                        ((FeatureLayer)c.Layer).Graphics.Remove(c.Graphic);
                }
            }
            else
                Debug.WriteLine("null graphic!");
        }
    }
    if (fLayer != null)
        fLayer.Update(); // this is a workaround
}

Thank you for your post. We'll consider this for future enhancement. For the meantime, you can subscribe to the layer's EndSaveEdits and maybe do the following:

private void FeatureLayer_EndSaveEdits(object sender, EndEditEventArgs e)
{
 if(e.Results== null|| e.Results.UpdateResults == null) return;
 FeatureLayer layer = sender as FeatureLayer;
 foreach (var item in e.Results.UpdateResults)
 {
  Graphic graphic = layer.Graphics.Where(g =>(int) g.Attributes[layer.LayerInfo.ObjectIdField] ==(int) item.ObjectID).First();
  //TODO: your code goes here
 }
}
