Hi,

I'm trying to add parameters to my dataset using the Generate Attribute operator. In some cases I want to include a missing value for my new attribute. I have tried the following expression: 
if(class=="y",FALSE,if(class=="x",?,TRUE))
Unfortunately this does not work. I hope someone can help me

Regards

Patrick
