Access of undefined property JSON

[ShaningYu]

In updating a project that compiled in FB 4.5 to 4.6, received such an error:
Description Resource Path Location Type 1120: Access of undefined property JSON
I referred to the thread at http://forums.arcgis.com/threads/52264-upgraded-to-Flex-Viewer-2.5-Flex-4.6-SDK-and-have-JSON-compil..., and updated the library:
   import com.esri.ags.utils.JSON;  //com.esri.serialization.json.JSON; V4.5
But still get the error for this piece of code:
  var dobj:Object = JSON.encode(ac);
Please provide your advice if you know how to fix it.  Thanks.

Shanning,

   Because both adobe and esri has a library with the same function you have to fully qualify the calls:

var dobj:Object = com.esri.ags.utils.JSON.encode(ac);

Robert -

   Any update for this for FlexViewer 3.6?  I leap-frogged a couple of versions and tried what was suggested above but still can't get the Viewer to compile ...

Thanks in advance!

Bob,

   If you grab the Viewer source from github and then just follow all the direction in this link to get started.
