    Exclamation TypeError: 'null' is not a constructor (evaluating 'new c(a[0])') with blank project

    1- I start a blank new EXTJS 4.0 project with Sencha Designer 2 Build: 311.
    2- I drag a Store in "Stores"
    3- I save and deploy

    I get TypeError: 'null' is not a constructor (evaluating 'new c(a[0])') in my browser console. I use Safari 5.1.4

    I tried everything I could and always get this error.

    How can I fix this?

    Can you archive your project and attach it here so we can have a look.

    File -> Archive Project

    update: coming from the Sencha Touch 2 world, I didn't know EXT4 project needed to be run under a web server (Touch projects can be accessed through file:/// and they run). So I started a webserver with "python -m SimpleHTTPServer" and got it to work.
