Thanks, Sanchit! I am learning subtle things like that as I go through these tutorials / examples.

That's why never start typing with domain prefix unless you are using an interface component or smart service (they all have a! domain prefix). When you start with a! domain it will only suggest functions which use that domain, so better start typing the function name directly. Happy coding 🙂

Mea culpa/apologies - I shouldn't have put the 'a!' in my code - I was trying to use 'a!joinarray' (realize it doesn't exist) when I should have been using 'joinarray'. I was using a!update and a!flatten as part of that code and didn't may close attention to the fact that joinarray doesn't have the 'a!' prefix.

it's the only one i know about 🤷🏻

Also, didn't you just say your 22.4 CE instance "doesn't allow" you to use it? I'm confused what you were referring to, then.

I didn't know about the regular joinArray.

Thanks

Yes, I assume you're missing something, but I have no idea what it might be - so please post the code you're attempting to use, and a screenshot showing it plus the result (and any other context). I've been using joinArray() since at least 2014 or so, and all Appian versions after that, so I am confident that our CE instances have it.

Edit: here's code and a resultant screenshot that I literally just typed into my 22.4 CE instance:

a!localVariables(
  
  local!arrayOfNumbers: {
    234235,
    45324052,
    8934,
    1,
    358905998
  },
  
  joinarray(local!arrayOfNumbers, ", ")
)

Mike,

If I understand you correctly, you are also suggesting that I should use joinArray? But for community edition 22.4, I can't seem to find a version that work. Am I missing something?

Dave,

Is there a version of a!joinArray I can use for 22.4? My 22.4 community edition doesn't allow me to use joinArray.

Yeah, the substitute approach seen here works, but also only kinda by accident - because by casting the array as a string using tostring(), you get Appian's plaintext rendering of the array with the "; " separators, then stripping those out using substitute. But that totally depends on the behavior of casting an array to a string, which I don't believe there's any particular guarantee will always behave the same way - so of course the cleaner way is handling the array itself, and not taking the extra intermediary steps.

Good to know the substitute approach, but yes I use joinArray() almost every day to do what you said, and I have for many years.

There is no "a!joinArray". There is regular "joinArray()" which has been around for many years now (long before any of the "22.x" versions). What's wrong with just using this, regular, joinArray()?

e.g.: joinArray(local!myList, ", ")

Found the answer - substitute(tostring(local!fdcIDSublist),";",",") does what I want
