Use MobileSDK in Angular. ConnectionObserver not work in my case

I am using angular and would like to get the MobileSDK(JavaScribt) running.

I have included the XPMobileSDK.js and I looked at the samples from Github and am trying to adapt the application.js. https://github.com/milestonesys/mipsdkmobile-web

The connection to the MobileServer, the login and GetAllViews seems to work. Then I use the requestStream method with the connectionId as in the example (application.js). The SuccessCallback is executed and I get the connection object. There I add an observer with a method like in the example. Unfortunately, this observer method is never called. How can I find out what is not working? In the browser console I get the message like in the JavaScript example: Server has prepared video ID c8ea8799-fdbd-4d55-8a5b-76273b186a5b

Hello Andreas,

It is very hard to predict what is happening with you code without seeing it. Can you please share it somehow so that we can analyze what is wrong.

Best regards

Teodor
