Error on FeatureLayer_Mouseover_Snapshot

MattJensen — Mon, 20 Jun 2011 21:51:34 GMT

I don't understand why I get the error "The prefix "esri" for element "esri:SimpleFillSymbol" is not bound." on line 68, when all I do is copy and past code from the original file to a new file?

Line          Code
68  <esri:SimpleFillSymbol id="mouseOverSymbol" alpha="0.5">
69   <esri:SimpleLineSymbol width="0" color="0xFF0000"/>
70  </esri:SimpleFillSymbol>
71  <esri:SimpleFillSymbol id="defaultsym" alpha="0.2">
72   <esri:SimpleLineSymbol width="1" color="0xEEEEEE"/>
73  </esri:SimpleFillSymbol>

The code looks to be bound to me

Thank you for your time,

Matt,

Do you have the

xmlns:esri="http://www.esri.com/2008/ags"

in the top most element?

Thanks, that was it.

Now I am trying to get the infoWindow to pull data from data that is loaded in an esri:featureLayer that I have loaded. To see what I have done click http://204.236.161.112/CBWS_MouseOver.html. I know I need to update "myTextArea.htmlText" but for the FIPS: I am trying to point to the correct field in my data. Here is a link to my published map services data http://204.236.161.112/ArcGIS/rest/services/CountyCombined-added/MapServer

I am ultimately trying to combine the mouse over with the table of contents (http://204.236.161.112/_CBWS03.html) and I need to show my legends in a pop-up window of sorts.
