DataDrop plugin

[threewonders]

Hello

I'm trying to prove by example that this in:

http://forums.ext.net/showthread.php...ataDrop-plugin

But do not get it to work. If commented ext: GenericPlugin the grid is fine.
On the other hand if I mention the screen remains blank and nothing is visible

            <Plugins>
                <ext:GenericPlugin 
                    runat="server"
                    InstanceName="Ext.ux.grid.DataDrop"
                    Singleton="true"
                    Path="Override.js,Ext.ux.plugins.DataDrop.js"
                    />
            </Plugins>

Js file are at the root of the application and the error details are as follows:

Message: 'Ext.ux.grid.DataDrop' is null or not an object

Thank you very much
