    Cool UDJC Can you have Multiple Info Streams as in More than 1 Info Step attached to UDJC?

    Hi,

    Just curious as I can make a UDJC work with one info stream but as soon as I add more than one I get errors.

    When you define the second info step:

    The first odd thing is that in the GUI you only see the fields from the first info step.

    If you run you get errors like "Unable to find Info field helper for field name 'FOO'" even though the field helper for FOO is defined in the code:

    at org.pentaho.di.trans.steps.userdefinedjavaclass.TransformClassBase.get(TransformClassBase.java:730)
    at Processor.processRow(Processor.java:137)
    at org.pentaho.di.trans.steps.userdefinedjavaclass.UserDefinedJavaClass.processRow(UserDefinedJavaClass.java:1182)
    at org.pentaho.di.trans.step.RunThread.run(RunThread.java:40)
    at java.lang.Thread.run(Unknown Source)

    I thought from the docs and info I have found that you could indeed have more that one info step attached to a UDJC.

    Think I'm wrong.

    PDI 4.2.1 Stable

    Thanks

    Kent

    While you wait for someone who knows, you could try to fuel curiosity of a bystander by preparing a toy transformation ...
    So long, and thanks for all the fish.

    I tried it and could not make it work ...
    Like I stated the names of the fields don't show up in the GUI under the info tab etc.
    Thanks
