PureEngage On-Premises

I'm trying to do intelligent list, when a certain value is selected in my first business attributes, I would like to be able to reduce the list of my second business attributes. I've tried to filter the CaseData.GraphicDataValue.List and CaseData.AdvancedConfig["list"] but nothing seems to be working. Any hint or solution?

Thanks.

After resetting your CaseData.AdvancedConfig["list"] with your filtered list, you need to call CaseData.ResetGraphicDataValueFromDataValue();
