How to change items in array property and render the change?

[istok20]

made it as:

Ember.set(item, 'caption', obj.caption);  
Ember.set(item, 'application', obj.application); 

that worked, many thanks!!!

could you also please help me with other interesting issue described here:

Chan.join(...).receive(...).receive(...).receive(...).after is not a function

why this code (from example of working code for phoenix <> ember websockets ) is not working? chan.join() .receive("error", resp => { console.log("error on JOIN", resp) } ) .receive("ignore", resp => { console.log("auth error", resp) } ) .receive("ok", resp => { console.log("join ok", resp) } ) .after(10000, resp => { console.log("Connection interruption", resp) }) I’m getting “chan.join(…).receive(…).receive(…).receive(…).after is not a …

MANY THANKS AGAIN!!!

ps: is it possible to observe both clientList.@each.caption and clientList.@each.application in the same computed property?
