Issue: a!isNullOrEmpty() not working with blank a!map()

While trying to check an empty map, a!isNullOrEmpty and a!isNotNullOrEmpty are not working, rather giving opposite result.

The result of

a!isNullOrEmpty(a!map())

should be true but the function is returning false. Not sure if this is a bug but something that might need the engineering team's attention. Peter Lewis

I have seen this happen multiple times within process models if we get an empty CDT map as a result and try to use this function to verify if it is empty. So I usually check one of the CDT's not null parameter…

I made this edge case part of my universal null check.

    if(
      local!typeNum = 'type!{http://www.appian.com/ae/types/2009}Map',
      /* Has no keys at all or all values are null */
      or(
        length(a!keys(ri!value)) = 0,
        all(a!isNullOrEmpty(_), index(ri!value, a!keys(ri!value), null))
      ),
