multiple then not fulfilled

[laoshu133]

var promise = Vue.Promise.resolve(1);
var x1;

promise.then(function (x) {
    x1 = x;
});

promise.then(function (x2) {
    console.log(x1 === x2, x1, x2);  // x2 is undefined
});

Same issue.

Subsequent then's are called, however the response is undefined for all but the first then.

confirmed here.

This is implemented intentionally, currently the promise chain does not break. Means your example code will actually work like this. Since the first then does not return anything.

var promise = Vue.Promise.resolve(1);
var x1;

promise.then(function (x) {
    x1 = x;
}).then(function (x2) {
    console.log(x1 === x2, x1, x2);  // x2 is undefined
});

This is useful, but sometimes I need to do some caching;
And this implemented does not follow "Promise A+".

I removed this in the develop branch, will be released with v0.9
