I am trying to concatenate a set of 20 datasets and use the "Append data source ID" option to retain visibility into which data element came from which input source.
The issue I am running into is that even though the input data tables have unique names in the UI (Unit A logs, Unit X logs, etc) the data info widget still displays the name of every data table as "untitled", and the Concatenate widget appends source ID's of "untitled (0)" and "untitled (1)" apparently based on the order in which the tables were connected to the Concatenate widget. I have a work-around using the Create Class widget to rename the Source ID, but this is very brittle.
Am I doing something wrong or should this be a bug report? Is there a mechanism for naming data tables that I can't find in the documentation?
Thanks for any help.
