Answer 1

You need 3 files for a working ExtJS system:

Development:

• ext-all-dev.js
• one language file from the locale folder (e.g. ext-lang-en_GB.js)
• one theme file from the resources/css folder (e.g. ext-all-neptune-debug.css)

Productive:

• ext-all.js
• one language file from the locale folder (e.g. ext-lang-en_GB.js)
• one theme file from the resources/css folder (e.g. ext-all-neptune.css)

the development files are not minified so you see where an exception occurs.
