The generated code is simply using the id field for the uid and it supposed use all the properties of the compound key. Because of this issue objectEquals of the BaseContext.as is failing and which leads to unexpected data.

This is what is currently bieng generated.
 
     public function get uid():String {
            if (!_id)
                return "com.pscufs.xtremecallcenter.ejb3.entity.CallTrackingRfcRfi";
            return "com.pscufs.xtremecallcenter.ejb3.entity.CallTrackingRfcRfi:" + String(_id);
       }
 
Code should be something like
 
        public function get uid():String {
            if (!_id)
                return "com.pscufs.xtremecallcenter.ejb3.entity.CallTrackingRfcRfi";
            return "com.pscufs.xtremecallcenter.ejb3.entity.CallTrackingRfcRfi:" + String(_id.callTrackingRfcId + '' + _id.callTrackingRfiId);
        }
