[Click] Sharing info between elements

[Dagang LI]

Hi Eddie & Ashwin,

Is using Handlers a better (recommanded) way over this kind of "direct 
remote function call"? e.g. get the name of the element via a 
configuration argument and then call its Handlers to access/manipulate 
its internal variables. I suppose it is cleaner and more consistant, but 
not sure if I understand the purpose of Handlers correctly.

Kind regards,
Dagang
