index or property function always returns default value in process model even when the property is in the bean(map)

Certified Associate Developer

Hello community,

I wonder if this a bug or I am doing something wrong.
we use Appian 20.4.

If I try to get the data of a map using index or property it always returns default value when present.
This behavior only occurs in the process model and not in a expression object.
e.g.
pv!testMap: a!map(errormessage: "something went wrong"),

then this code property(pv!testMap, "errormessage",  "default") or the same using Index function.
Will return "default".

dot notation works: pv!testMap.errormessage wil return: "something went wrong".
property or index without a default works: property(pv!testMap, "errormessage") wil return: something went wrong".

Maybe I overlook something, got it working by the way by casting the map to a map but that makes no sense off course.

Kind Regards,

Erik
