Deferred Error Testing

Deferred.js

	], function(Deferred){


	var useError = 0	;
	var getError = function(name, useThisError){
		var msg = name + ' error';

	}

	var d = new Deferred();

	d
	.then(
		  doZap,
			getError('zap'), 0)

	.then(
		doBar, // throws an error
		function(e){ console.error('e bar'); d.reject(e); }) // does not get called

	.then(
		  doFoo,
		  getError('foo'), 0)


	d.resolve();

	console.log('rejected:', d.isRejected(), 'fullfilled:', d.isFulfilled()); // not correct
});
