#873 ✓invalid

Hash declared in a class definition is shared between class instances

Reported by batman42ca | March 20th, 2010 @ 10:00 PM

When I declare a Hash like this inside my class:

var MyObj = new Class({
  myHash : new Hash()

All instances of MyObj share the same Hash.

see this for a working example:

This came as a BIG surprise (after a few hours of debugging)

    This is the correct behavior.

    If you wish to have a different hash at each instance you can do this:

    var MyObj = new Class({
      initialize: function(){
        this.myHash = new Hash();

    each instance of MyObj will have a new, different, Hash object.
