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.
