I see some samples use Ext.grid.EditorGridPane. I tried the sample, but it seems can't find the class in my environment.
I use EXT JS 4.0.2a, and have ext-all-debug.js included.
I searched whole EXT JS installation, and don't see Ext.grid.EditorGridPane located anywhere.
Is it a "standard" EXT JS class? If not, why it come with a Ext.grid package name?
