How do I fix "Add myBundle to the asseticBundle config" symfony2 exception?

Yes I tried and it solved the issue for me. For someone (like me) who doesn't know initially how to add then just:

1. edit app/config/config.yml
2. then go to assetic:
3. under assetic: go to bundles: []
4. and in bundles: [] //type your bundle name

for instance if your bundle is Acme\DemoBundle, then do the following

assetic:
   bundles: [ AcmeDemoBundle ]

No quotes around AcmeDemoBundle. That's it. (Symfony2)

If you want assetic to include your bundles by default, you can comment (with #) the line bundles: []

ex:

assetic:
    debug:          "%kernel.debug%"
    use_controller: false
    #bundles:        [ ]
    #java: /usr/bin/java
