I saw a post asking for filters feature using SA.
Find an incomplete "port" of "Custom Grid Filters Example" ( http://cdn.sencha.com/ext-4.1.1a-gpl...ter-local.html ) to Sencha Architect.
Note that I have to change Ext.ux.grid.menu.ListMenu.js +/- line 53 to make it work.
Hope this helps everybody to exploit SA.
Feel free to ask anything about this port.
Add css resorces and, I don't know why, my modification of ListMenu.js disappeared.
