Re: Finding out when actionLink action is completed on the user side

Sure, the equivalent in 5.3 is to use t:zone or better: write a mixin and add a custom listener to your link.
I once wrote a very generic mixin that you can use as click or change (or any event) listener:

I think there are also similar examples to be found here: http://jumpstart.doublenegative.com.au/jumpstart/examples/input/atonevent/0
