I'm looking for a way to show an alert / a notification / a popup or similar for the user which has been assigned a task? It should be nearly real time, that is if user have browser window open it must be shown instantly after the task has been assigned. Is it possible at all? Alternatives?
I assume it has something to do with the triggers, programming apex class and designing a view in the visualforce?
Could someone put me on the right path please?
I'm not new to various programming paradigms, just not sure where or how to start in the salesforce.
