Need to understand the difference between the usage of the rules APN_isEmpty and APN_isBlank

isEmpty check whether a value is null or an empty list. isBlank checks for null and an empty string.

I do not use these expressions and recommend to use the new a!isNullOrEmpty function

Hi All,

Really very helpful suggestions and solutions .

One thing I did not understand. What is "singlePV"

I don't see this exact term used anywhere prior in this thread, or even at Stefan's link - can you clarify what you're referring to?  Without any other context I'd guess it's referring to a PV of "single" type, i.e. not an array (aka "multiple"), but that's just a blind guess at this point.

Hi Stefan,
Agree that they're not necessary anymore. 
Please hear my current scenario and give me a hint: i have to import 2 applications in a fresh cloud environment, and I miss the APN_isBlank() and APN_isEmpty() precedent rules (they weren't included in the packages with applciation objects).
Can you please let me know where I might find them? are they in market place? I'm not able to find them anymore like in the old days on Appian Forum.
I've a support ticket open about that but no answer so far.
Thanks!

Search old posts - I (among others) may have posted small app packages here or there containing just these or a similarly small set of the old common objects rules.

I was able to create a consolidated fresh 21.4 export of both the original legacy APN_isBlank and APN_isEmpty rules (But only these two), along with all necessary precedent folders.   PFA.

Thanks!
