Hi
Thanks for all suggestions.
Will it not be possible to evaluate expression rule that returns custom data type from Smart service / Filter code?
I need to evaluate an expression rule inside Filter class, so i can not pass it as process parameter. So I created the below expression rule named EI_TESTRULE with rule definition:
='type!{bac.com/entitlement/AppianGroup}AppianGroupConfig'(
appianApplicationName: "Test",
appianGroupName: "Test",
appianParentGroupName: "Test",
appianCustomGroupType: "Test",
appianGroupSecurityType: "Test",
appianGroupMemberPolicyType: "Test",
appianGroupPrivacyPolicyType: "Test"
)
and it worked when i tested it from Appian designer portal.
I have imported this package to my filter (it got imported as com.bac.entitlement.AppianGroup.AppianGroupConfig.java class).
and I tried to get this expression rule evaluated in my filter class using the below code:

Thanks Ed for your suggestions. I have imported the complex data type already. My project requirement is to read the values of a complex data type set in Appian from Authentication Filter. I am using this filter for customizations at the time of user login. Since there is no way in a filter to read user input values, I have created an expression rule in Appian Rules tab which when evaluated returns a custom data type ( with values set) and I want those values to be read from filter.
I used ProcessDesignService.evaluateExpression but I got the error:
com.appiancorp.process.expression.ExpressionRuntimeException$AppianExceptionProvider: Expression evaluation error : Rule ei_appiangroupconfig_constant has invalid form, so cannot be evaluated (APNX-1-4198-000)
Pds.evaluateExpression works if the expression rule returns a TEXT data type, but DOES NOT WORK when the rule returns a complex CDT object.
Is there a way to read a CDT object values from Java (Filter / Smart services)?
Thanks
