Well I use this code:
to get updated value when attr1 and att2 are updated, then I want to place this value to some scope attribute.
To do this I handle compute change in events
I could also do this with events, but I don't like such approach, esp when there are more then two "base" attributes (attr1 and attr2).
Is there any other way to complete this besides my first option (with compute and event handler for it)?
