    Ext.create, constructors, and config

    Apologies if this has come up before. I'm fairly new to ST, but I feel I'm beginning to get it. The concept of configurations that automatically generate getters and setters (plus the apply and...

  11. Showing class names in the debugger (rather than Ext.apply.create.Class)

    The new class system is nice, but it makes it tougher to debug since an instance of any class is labeled as 'Ext.apply.create.Class' in the debugger. In pure JS, it was very simple - you just added a...
