Katya, thank you.
But if I specify as component name - Screen, then I cannot continue. Does this mean that I should link the local storage value to particular screen element? If yes - then what element should i use?

Could you please help me with another thing - what is the right way to display specific to this "task" data?
So: I have task, then I want to display when, say, it was created - how should i do this? Should I use service 'read service' on that page? If yes then - what should i use as a variable for it? i mean that i can use id (but where should i get it from?) - or should i use the local variable? If yes - then there could be the case when is not unique?
