             Summary: Wrong transformapply output with col name specification and subset of cols
                 Key: SYSTEMML-1824
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-1824
             Project: SystemML
          Issue Type: Bug
            Reporter: Matthias Boehm


Given a frame input with column names {{name1, name2}}, the following script produces incorrect results:
{code}
X = read("X.csv", data_type="frame", format="csv", header=TRUE);
spec = "{ids: false, recode: [ name1, name2 ]}";
[Y,M] = transformencode(target=X, spec=spec);
spec2 = "{ids: false, recode: [ name2 ]}";
Z = transformapply(target=X[,2], spec=spec2, meta=M)
print(toString(Z));
{code}

The output is supposed to be 1x3 and properly recoded but currently returns
{code}
NaN
NaN
NaN
{code}
