You need to share the same instance of can.Observe list between your controls. The easiest way is passing them as options:
- 'init': {
- this.items = can.Observe.List([]);
- this.items.attr(getFromSomewhereAListOfObjects);
- this.b = new B({
- items: this.items
- });
- }
Now you can access `this.options.items` in Control B e.g. do something like
- this.items = this.options.items;
During initialization.
