hi, all,

I don't have much experience on Flex, and I met this problem when I try to
open my mxml on Tomcat:
Could not resolve <mx:AdvancedDataGrid>

My flex build version is version 3.0 (bulid 3.0.194161) while my lcds version
is Flex 2.0.1 Hotfix 2 build 166910 (according to flex-sdk-description.xml). I
know that ADG is a part of new feature in Flex 3, just don't know if it is
possible to make my application work by migrating or editing some files.

I saw some articles about this problem and tried several ways, say like copy
the datavisualization.swc into the lib directory under project, but doesn't
work.

Is this problem reported as bug? [url]http://bugs.adobe.com/jira/browse/SDK-12719[/url]

and is there any solution to this problem?

Many thanks for any comments.
