Description

The frame transformapply is failing if the transform specification requests a mix of recoded and dummy coded features. For example, consider the following transform spec on the homes dataset:

{ "recode": [ "district", "zipcode", "view" ], 
 "dummycode": [ "zipcode" ] }

generates the following exception:
