Update this example from Flex API 1.3 to 2.2

DylanRoy

Hello,
I was wondering if anyone was able to update this example that uses the Flex 1.3 API to the most current version. Query no longer exists and it seems to be QueryTask's predecessor. If I get it converted I will post it in a reply.

Thanks!

Dylan,

   A little reading in the documentation will tell you that two of the import statements in this sample have changed

import com.esri.ags.tasks.supportClasses.Query;
   import com.esri.ags.FeatureSet;

Once you change the samples existing imports to the ones listed above the sample will work again.

Supporting classes in the Tasks package has moved into a subpackage com.esri.ags.tasks.supportClasses, except for FeatureSet which is now in com.esri.ags.FeatureSet.
