Are you using 1.6+ ?
The correct syntax for defining a "class" has changed since 1.5:

var ReadHash = Class.create({
        initialize: function(data){
                this.data=data;
        },
        read: function(){
                this.data.each(function(pair) {
                        alert(pair.key + ' = "' + pair.value + '"');
                });
        }
});

var ReadMyData = Class.create(ReadHash, {
        initialize: function(data){
                this.data=data;
        }
});

var TestReadHash = new ReadMyData($H({ var1: 'foo1', var2: 'foo2' }));
TestReadHash.read(); // works as expected

Hope this helps.

P.S. please, post futher question at support mailing list

development related.

Best,
