How can i resolve two distinct promises in a protractor test?

I am a beginner with Node.js. I have a promise that downloads a file from a server, then parses it into a json object and returns it. Another promise returns a webpage element(). The two promises have to be solved one after another: first the promise that returns json object,this work good, then the promise that gets the page element. Using a key from the json object i have to test if the element contains the same text.

Code:

var menuItems = element(by.id('menu')).all(by.tagName('li'));

it('should contain', function (done) {
  jsonPromise.then(function () { // work
    console.log('Inside jsonPromise then');
    menuItems.then(function () { //------> not step into
      console.log('Inside menuItems then');
      expect(menuItems.get(0).getText()).toEqual(jsonData.home);
      done();
    });
  });
});

With this code protractor returns: 1 test, 0 assertions, 0 failures Why is that? What am i doing wrong?

Note: both console command execute

You need to put the jsonPromise on the protractor's Control Flow:

browser.controlFlow().await(jsonPromise).then(function (data) {
    expect(menuItems.first().getText()).toEqual(data.home);
});

With protractor 2.0.0 WebElements element does not return a Promise

This should work

menuItems = element(by.id('menu')).all(by.tagName('li'));

describe('my tests', function(){
  it('should contain', function(done) {
    jsonPromise.then(function(jsonData) { 
      console.log('Inside jsonPromise then');
      expect(menuItems.get(0).getText()).toEqual(jsonData.home);
    })
    .then(done)
    .catch(done);
    // if using jasmine2 it will be .catch(done.fail)
  });
});
