Action Process Function Evaluator Activity doesn't work when using only one field, but when I concatenate with 2 it works.
Create an action Process
Add one activity -- Function Evaluator
Set a destination to an attribute (like DisplayName) and select only one field in the value -- LastName
Then build an MPR to apply to All People (don't check Grants Permission), Operations: Create and Modify
Requestors: All People
Condition Before All People
Condition After All People
Policy Workflows: Add your Action Process
Then create or modify a user
open the user again and note that it did not work
Then look at search requests, view the request and note the following error: Data at the root level is invalid. Line 1, position 1.
and when used gives this error:
But this works (as does concatenating with a "" string)
Please repro and validate as a bug
