Hi Champ,

I have a use case where I am getting the constnat name (in text) and I have to pass that in Update constant service. But here the issue here is I am unable to pass the constnat name dynamically there. As the name is text type and it's expecting something of constant type. I don't see any option to cast it too. Only way possible here is selecting consttant from the menu ; but I can't do that as it's dynamic in my case.

I'm sorry, but YOu won't be able to do what you want.. Appian is limited in that way...IN the same way for example, you can't invoque an interface or subprocess passing the name or id as a parameter

I had written a plugin to do this many years ago, ("Constant Utilities" - getConstantObjectByName() ) but looks like it's not available on the appmarket any more. Was pretty simple implementation, though.

This is not a good idea at all.  Constants (as well as rules, interfaces, etc) can now be re-named by any designer with sufficient editing access, and as such, if you were to work out some override in order to use this method of referencing a constant in this smart service, it would instantly break if it were ever renamed by a different designer (and there would be no warning to them or any other way to know they're about to break it).
