             Summary: Transformdecode fails with index out of bounds
                 Key: SYSTEMML-2254
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-2254
             Project: SystemML
          Issue Type: Bug
            Reporter: Matthias Boehm


Given a meta data frame M, and a single column input matrix, {{transformdecode}} fails with
index out of bounds due to unnecessary pass-through decoders.

{code}
# THIS FAILS with Caused by: java.lang.ArrayIndexOutOfBoundsException: 142
# foo = transformdecode (target=seq(1, 142), spec="{ids:true,recode:[1]}", meta=M)      
# THIS WORKS
foo = transformdecode (target=seq(1, 142), spec="{ids:true,recode:[1]}", meta=M[,1])
{code}
