Hi

I need to evaluate an expression rule from my smart service. I could able to get the expression rule id through ContentService.searchByRoot(rulesRootId, ruleName, filter)
and I got an object of type FreeformRule and i can get the expression rule id from that object.
I need to evaluate this rule and get the results which return a custom data type.

I tried to use ExpressionService.evaluateExpression, but it is deprecated method. In processDesignService.evaluateExpression takes java.lang.String Expression as parameter, not expression rule id.
Please suggest me with suitable api that takes expression rule id as parameter and return results
Thanks
Jhothi

There are a lot of examples in the Shared Components of custom functions and smart services that use Complex Data Types, you don't need to evaluate an expression, you simply import the complex data type as a POJO into your Appian Java Project and you build the instance of the data type as any Java object.

As you can see in those examples there is no need to evaluate an expression to build your Complex Data Type.
