thanks !

It’s Monday morning and I’ve got “this.addEvents is not a function” error and spend like 30 minutes without figuring out where it comes from.

Have a nice week!

This is excellent – I have a draft post of my own with the same concept and a practically identical set of errors

I’d add that the this.addEvents error crops up if you’re trying to define new events on an extended component before calling the superclass constructor, which has tripped me up a few times…

It’s a silly mistake to make, but then they always are!

Very good post, will bookmark and maybe even print and stick to my wall! @Ed how about a mini project to make friendler error messages!! Then posts like this won’t even be necessary…

I came across this Googling a f.convert error. Thanks to this post I was able to spot my mistake of “type: ‘data’” instead of “date”.

I’m just happy that ExtJS apparently has a fair amount of specific error messages built-in, and that I don’t have to rely just on JavaScript ones.

Though, the first part of your post made me realize something — I, a long time ago, made a sophisticated wrapper to the entire grid system in ExtJS (to work with the datasets I get), and I’ve long since forgotten how the ColumnModel even works. :\ That’s ridiculous.
