I have 3 services that return 3 promises, but the third needs the data from the second, so I call it inside the second. I want to wait for all the three promises to be solved, this is the way that I implemented, but doesn't work (waits only for the first and the second).
var promise1, promise2, promise3;
promise1 = service1();
promise2 = service2();
promise2.then(function (data) {
promise3= service3(data);
});
$q.all([ promise1, promise2, promise3]).then(function success() {
//somehing
});

Reset to default 18You can assign the second promise's then() callback with a returned promise from the third service.
var promise1, promise2, promise3;
promise1 = service1();
promise2 = service2();
promise3 = promise2.then(function (data) {
return service3(data);
});
$q.all([ promise1, promise2, promise3]).then(function success() {
//somehing
});
Have you tried to nest your promise 2 inside promise 1, and then put your final resolve inside the promise 3 delegate?
That's pretty slick code and I'm certainly no expert, but have had to wait to accomplish things on other service calls and have had to do things like that.
