Sherly,

That error comes when you are missing an import in your code, and because you have not attached all of the code it is impossible to say which import you are missing.

sherly,

Which Adobe Flex SDK are you using and What ESRI Flex API?

Re: Error #1010: A term is undefined and has no properties.

sherlytobias — Mon, 27 Feb 2012 04:34:24 GMT

I am using Flex SDK 4.5.1 and ArcGIS API for Flex 2.5. Sir, can you tell me what am I doing wrong? Thanks in advance.

RobertScheitlin__GISP — Sat, 11 Dec 2021 22:08:58 GMT

Sherly,

A couple of points.

A geometry is not going to project if it never knows what spatial reference it is in to begin with (which is your case)
```
myPoint = new MapPoint(latlong);
```

The MapPoint constructor is expecting a minimum of two properties x and y normally it would look like
```
myPoint = new MapPoint(xCoord, Ycoord);
```
You are trying to feed it one Number and no Spatial Reference.

Try this if your points are in WGS 1984:

var latlong:Array = node.point.toString().split(" ");
                myPoint = new MapPoint(latlong[0],latlong[1], new SpatialReference(4326));

Sherly,

Try this:

var x:XML = XML(event.result);
for each (var node:XML in x);
