Flex: Get Graphic SHAPE.len Attribute

TylerWaring — Mon, 03 Oct 2011 14:12:23 GMT

Greetigns Everyone,
I am trying to work with the SHAPE.len field in the Flex Viewer so that I can serve up to date length data for a linear feature layer. I assumed that I could get it in the same way that I usually get attributes:

var nmLengthFeet:Number = graphic.attributes.SHAPE.len;

Seems not to be working though.

Any Ideas?

Best Regards,
Tyler Waring

Since Shape.Len is an internal ArcGIS function, it's not an actual attribute that you can grab hold of. You'll have to create your own length field.

I guess I'll have to make an update script then. Thanks for the tip.

You can access the Shape.len field, but you'll need to use bracket notation since the "." won't translate over in code.
I tested this and it works with my SDE data.

var query:Query = new Query();
query.outFields = ["*"];
query.returnGeometry = false;
query.where = "AssetID  <> ' '";
var queryTask:QueryTask = new QueryTask("http://testgis/ArcGIS/rest/services/SewerSystemTest/MapServer/5");
queryTask.execute(query, new mx.rpc.Responder(function(features:FeatureSet):void {
 for each(var o:Object in features.attributes)
 {
  trace(o["Shape.len"]);
 }
}, function(fault:FaultEvent):void{ trace("error", fault.message); }));

Thanks for correcting me, Rene. I had forgotten about the fields in SDE.

I tried using attributes['SHAPE.LEN'] and it doesn't work for me.
