This is my code, and i always get "Success/error was not called" but i expected the end of my code waiting until ALL promises are resolved or rejected? Am i right?
SHORT Example how my code looks like (scroll a little bit more, for full code):
var promises = [];
for (var i = 0; i < 100; i++) {
promises[i] = new Parse.Promise();
if (i < 50) {
someAsyncParseFunctions() {
promises[i].resolve(i + "worked");
}
} else {
someAsyncParseFunctions() {
promises[i].reject(i + "doesnt work");
}
}
}
Parse.Promise.when(promises).then(function() {
response.success("All worked");
}, function(err) {
response.error(err.message);
});
Full code:

Would be nice if some of you could help me fixing this! I realy tried much! Maybe it's only a small error from my side!
