    Default ARFF output plugin to working with variables to define file names

    I'm working on a project to predict supplier responses for a client that operates internationally. The output is always the same, as is the training dataset. However due to big differences per region, we need to generate unique models per region.

    What I would like to do is use a generic PDI transformation to export the multiple region-datasets to ARFF files which I can proces separately using WEKA.

    With other output formats I'd use a transformation parameter in the filename, however I cannot get this working with the ARFF output plugin. The plugin is always using the transformation defaults. An Excel writer in the same transformation respects the input.

    Does anybody has suggestions to solve this? Or is it a known bug?

    I tried the ARFF plugin from the market place, the one linked on the community doc and the 6.1 and 7 versions form this Jenkins.
    Calling the transformation:

    This is probably a bug. Please create a JIRA ticket (with steps to reproduce) at:
