MyApp.aSimpleController= SC.ObjectController.create({
  contentBinding : SC.Binding.single('MyApp.anArrayController.selection')
});

MyApp.anotherArrayController= SC.ArrayController.create({
  abcBinding: 'MyApp.aSimpleController.content',
  xyzBinding: SC.Binding.oneWay('MyApp.anotherObjectController.content'),
  observeMe: function(){
    var abc= this.get('abc');
    var xyz= this.get('xyz');

Creating the record: 
     var record = Rapid.store.createRecord(Rapid.Check, {
        guid: '@123'
      });
 relationA.get('checks').pushObject(record);
... set up an observer on record status
Rapid.store.commitRecords();

the record is created, but relationA.checks points to @123 instead of the storeKey's id (1000)

I'm trying to reuse a query object:
 
   var q = this._q;
    if (!q){
      q = this._q = SC.Query.create({
        recordType: Rapid.Application
      });
    }
    q.set('conditions', 'currentStep = %@');
    q.set('parameters', [this.get('content')]);
