All the ExtJS documentation and examples I have read suggest calling superclass methods like this: MyApp.MyPanel = Ext.extend(Ext.Panel, { initComponent: function() { // do something MyPanel specific here...

I have created a Model class where I define methods based on a method (attribute) called in User (which inherits from Model). The problem is that I cannot override the method defined by define_method, and call super to pass to the defined method. I guess this is because the defined method is added to User itself, and not to the Model, so...
Smalltalk superclass vs metaclass ???
I new to OOP, but with a "procedural" background. I'm currently trying to get my head around OOP via GNU Smalltalk and Lovejoy's "Smalltalk: Getting The Message". I'm confused as to the the heck the metaclass and Metaclass class are, vs superclass. I can see the inheritance flow of superclass -> class -> subclass; but I don't see how/...

I have something like this going on in my Java program: void f(Object o) { g(o); } <T extends MySuperClass & MyInterface> void g(T x) { ...; } How can I cast o so that this works?

Use super class's address/pointer in initialization list
