It's for a school project for the next week so..
Anyway, I tried the sandbox (simple viewport with extjs 4, and on the center region an item:
(I copied / paste this code from windows calendar example) and i got an error in ext-all-sandbox.js: "namespace is undefined" .
// xtype is supported:
It's came from the xtype . (When I comment xtype... the error disapear ).
I also try : " xtype: 'Ext.ensible.cal.CalendarPanel',"
any idea ?
Sorry for my bad english...
