Thread: starting transformation does not function, debugging it makes it start

  1. #1

    Default starting transformation does not function, debugging it makes it start

    With version 4.4.0 I have this particular transformation that does not start from spoon when issueing the 'run this transformation' button, but using the debug button effectively start the transformation without any problems.

    The transformation itself fires 5 webservice calls in parallel from a single datagrid ('add constant rows') that starts the transformation with a dummy row.

    Could this be a bug?

    What about a screenshot showing just the steps you described?

    Sometimes running in debug works because you are not using the same variables in both execution. For instance, if using a slave server, maybe the distant server kettle.properties file is different from the local one (the one the debug will consider).

    Basically everything is fixed, no variables are used. Every other transformation can be started from Spoon except this one..

    Running the transformation by using it within a job does work normally..

    You might find an explanation for the observed behavior, if you stare at the source code long enough.
    I regard a transformation with separated data flows as an anomaly.
    Even if you don't hurt yourself, nothing's gained either.
    My recommendation: Split this up into separate transformations.
    So long, and thanks for all the fish.
