Hard to diagnose 'Unsupported InputColumn type' error when reading an invalid job

[kaspersorensen]

I am right now trying to figure out what this means in a specific case where a job has 5-10 transformers where this could theoretically be happening:

Unsupported InputColumn type: class java.lang.Object, expected: interface java.util.Map
    org.datacleaner.job.builder.AbstractComponentBuilder.addInputColumns(AbstractComponentBuilder.java:474)
    org.datacleaner.job.JaxbJobReader.applyInputColumns(JaxbJobReader.java:840)
    org.datacleaner.job.JaxbJobReader.wireInputColumns(JaxbJobReader.java:618)
    org.datacleaner.job.JaxbJobReader.create(JaxbJobReader.java:465)
    org.datacleaner.job.JaxbJobReader.create(JaxbJobReader.java:397)
    org.datacleaner.job.JaxbJobReader.create(JaxbJobReader.java:328)
    org.datacleaner.job.JaxbJobReader.create(JaxbJobReader.java:307)
    org.datacleaner.actions.OpenAnalysisJobActionListener.openAnalysisJob(OpenAnalysisJobActionListener.java:188)

Since the stack trace and exception message does not mention which component it happens for, I am a bit lost. So let's add the information we have available about the component to make the error easier to digest.

@kaspersorensen I guess that in the context of the issue you just want the logging to be improved, so that it also logs for which component/transformer this happens. Is that correct?

[kaspersorensen]

Yes it would be good if it could tell something about what component it fails on etc. Maybe even an XML snippet, although that may be optimistic from my side :-)
