> 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:
> {code}
> { "recode": [ "district", "zipcode", "view" ],
> "dummycode": [ "zipcode" ] }
> {code}
> generates the following exception:
> {code}
> Caused by: java.lang.NumberFormatException: For input string: "west"
