Ionic 2 - this keyword is undefined when promise is returned from data service

[iignatov]

I guess that maybe the arrow functions are still not supported in Chrome Dev Tools and that’s why this inside of them is reported as undefined. It seems that the updates to the properties are not being detected by Angular. This might be related to the following issue (you can try the workaround in this topic, it should fix the problem):

Since the Beta 4, my views don't update

@iborik Ok, thanks for the clarification. I created a new test environment which allows to run only a single test at a time. I retried all the tests and they are all working as expected. When I try the same thing with my test project locally then the platform test (i.e. platform.ready().then()) is not working. Do you experience the same, i.e. does only the platform test fail or all of them?
