Tracking where I am inside a workflow

I am trying to write a node for error logging. I would like the logging to include the sequence of nodes that led to the current point. What is the most straightforward way to do this? I have managed to parse the workflow directories and the workflow.knime to build the connection tree and the node identifications. However, there isn't an obvious way to map Wrapped nodes and metanodes just form the connection IDs as these files do not give the connection between the WrappedNode Input and Output and their actual nodes one level up.

Hi David,

so your goals is to write your own KNIME node for doing this? Than this would be more a developer question.

If you want, I will move your topic to this subforum.

Best, Iris
