    Default Transformation executor driving me nuts

    I am excited about the Transformation Executor step in 5.0.1 but running into trouble getting it to work.

    I have simplified the heck out of it to spike out a test but still cannot figure out what my little brain is not getting.

    I have a DB query pulling back 3000 rows, the stream is copied to a Text Output step and to a Transformation Executor. It happily writes to the text file but bombs on the Transformation Executor. The TE is going to three dummy steps just to keep it simple (for the three possible output streams result files, row and execution).

    I have simplified the transform being called so it only gets a single record back and does not even use the rows being passed in.

    I've tried just routing the execution results to try to keep things simple (no rows or file names coming back).

    No matter what i do the called transform seems to initialize all of its objects and then I get this very informative error:

    Code:
    2013/11/22 14:52:20 - Transformation Executor.0 - ERROR (version 5.0.1-stable, build 1 from 2013-11-15_16-08-58 by buildguy) : Unexpected error2013/11/22 14:52:20 - Transformation Executor.0 - ERROR (version 5.0.1-stable, build 1 from 2013-11-15_16-08-58 by buildguy) : org.pentaho.di.core.exception.KettleException:

    Any thoughts would be greatly appreciated. If I could get it to run under any conditions I think i could figure it out from there.

    Thanks again,

    I'm having the same issue, so I raised this jira. I hope samples can be provided to show how it should work!

    FYI:
    Started basic documentation:
    http://wiki.pentaho.com/display/EAI/...ation+Executor
    Added an (almost) working sample (tested on 5.0.6) to http://jira.pentaho.com/browse/PDI-12204
