API for Flex tutorial

[DustinHolt]

I'm doing a tutorial on the API for Flex using flash builder and I'm having a problem. In this exercise I'm creating a cached map service with a tiled map service as the base map, and setting the extent. I have followed the tutorial to the tea, but I keep getting "Object is not assigned". Can anyone see where I'm going wrong.

Dustin,

I cannot see where the louisville extent is being set, try removing the load="map.extent = louisville.fullextent"

Regards

Anthony

It works now, I don't now why they tried to do it that way. Thanks

Dustin,

  Where is this Flex Tutorial located?

If your code looks like this it works fine:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark"

    <esri:Map id="map">

        <esri:ArcGISDynamicMapServiceLayer id="louisville" url="http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Louisville/LOJIC_LandRecords_Louisville/MapServer" load="{map.extent = louisville.fullExtent}"/>
    </esri:Map>

Here is a PDF of the exercise.

Dustin,

   You will notice (upon close observation) that the changes I indicated are included in the exercise steps.

and give it an ???id??? of ???louisville???.

load="{map.extent = louisville.fullExtent}"

Flex is a case sensitive language so you have to be very cautious of that fact.

I found where I went wrong now. I had the "load="{map.extent = louisville.fullExtent}"/>" as a separate line, when it should have been a part of the "<esri:ArcGISDynamicMapServiceLayer" line.

Thanks Robert

Dustin,

   I went back and returned the answer credit to Anthony as he was the one that originally answered your question. I just wanted to add additional questions and comments, not take his points.

Yes, Thanks Anthony.
