SA-29234

Summary

A function is written to return "false" in case the value is not set, so Boolean property is used that will return 'true' only if the value is not null in all other cases it returns 'false' in Pega 7.1.5.
 
After upgrade to Pega 7.2 there is no change to any of the configuration in terms of DB / Property / Report Definition / Function Alias but an error is seen and report is not getting executed. 

Error Messages

pzInvalidAliasFnParam TRUEFALSE

STEPS TO REPRODUCE
​
1. Create a function alias with parameters of data type true or false. 
2. Execute the function alias from report definition.

Root Cause

While doing parameter validation for Function aliases, TRUEFALSE type is missed and throwing validation exception.
There was some re factoring happened after Pega 7.1.5 and broken.
