[quote=“abishur”]Because I’m not?[/quote]OK. I misunderstood. I’m going to assume your original example, given just the NAME_POPUP custom property, has bindings for the values like so:Indirect for Value: tagDB/{1}_CLOCK_DOW
Indirect for Alarm: tagDB/{1}_CLOCK_DOW.AlertActive
Indirect for Ack: tagDB/{1}_CLOCK_DOW.AlertAcknowledgedIn the indirect assignment for {1}, you have {Root Container.NAME_POPUP} for all three bindings. When you open the popup window, you only pass NAME_POPUP.
To your question: Yes, indirect binding as above can be expected to be faster/more efficient than an expression with tag() and concat().
