Executing a rule whose name is saved in a DB column from Process Model Script Node's Expression

May I ask what you want to achieve?

BTW, eval() is a not supported private function and should not be used.

Thanks Stefan Helzle, I am aware that eval is an internal function. I couldn't find another way though. We are trying to execute dynamic rules here. This implementation supports number of countries with each country has a different mapping rule. Hope that makes sense.

Your best bet is to create a mapping rule in Appian that calls the rule that corresponds to whatever text value you store in the database. For instance:

choose(
  wherecontains(
    ri!ruleName,
    {"ruleOne", "ruleTwo", "ruleThree"}
  ),
  rule!ruleOne,
  rule!ruleTwo,
  rule!ruleThree
)

Please do not use the eval function - it is undocumented, unsupported, and is not guaranteed to behave in the manner you want or expect.

Thanks a lot Peter Lewis. worked like a charm !!
