Hi Harry, I took a closer look to your screenshot. (BTW, pasting snippets as code makes it easier to spot issues and help you) It is a 'this' problem indeed. In JS, each function had it's own 'this' That means the 'this' in the function, is not your class. Hence the error. Replace the function with an arrow function, and your problem will be gone.
.then( devices => this.choseScale(devices)) should do the trick. Regards Sander -- You received this message because you are subscribed to the Google Groups "Angular and AngularJS discussion" group.
