Useful. I hope lots of people read this!

Don’t forget to add *callback* specifications.

Whenever you specify a function as a callback (eg, Store’s “load” callback), you might need to also specify scope, if the function expects to be a “member” of anything.

Thanks for sharing your Scope Donkey! Luckily, the ExtJS docs also do a pretty good job of documenting all the places where you can pass scope into their api.

Don’t forget the listeners config version of adding events

listeners: {<br /> myevent: this.myHandler,<br /> scope: this<br /> }
