             Summary: Transformencode failing for mix of recode/dummycode features
                 Key: SYSTEMML-1902
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-1902
             Project: SystemML
          Issue Type: Bug
            Reporter: Matthias Boehm


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}
