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.

[RobertScheitlin__GISP]

sherly,

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

[sherlytobias]

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.

[sherlytobias]

The error is gone now but i still can't project my points to the map. Please Help.

Here's what my xml looks like:

<feed>
<entry>
<point>46.47506 7.293239</point> 
</entry>

<entry>
  <point>46.424827 7.322059</point>
</entry>
.........

</feed>

[RobertScheitlin__GISP]

Sherly,

   A couple of points.

1. 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);



2. 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));

Don't forget to click the Mark as answer check and to click the top arrow (promote) as shown below:

and the error comes from this line of code:

for each (var node:XML in event.result.feed.entry);

[RobertScheitlin__GISP]

Sherly,

  Try this:

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

[sherlytobias]

The error is gone now but the points are still not projected. I can't think of anything to do now. It seems like my codes are correct but nothing happens. Please help. 😞
