I can not execute my workflow in batch mode or using right click in the KNIME explorer.
The workflow uses a subnode for cleansing data in a recursive loop. (the loop uses a dictionary to replace terms)
Next node is "Strings to document node".
> data base reader > cleansing of data (including loop) > Strings To Document (red) > further processing
If I did not execute the workflow until the loops end, I get the error message when opening the properties of Strings to document node: "The dialog can not be opened for the following reasons: No column in spec compatible to String Value". The node status is red.
I can right click and execute on String Value node anyway and the complete workflow runs through.
But I can not right click in the KNIME Explorer to execute the complet workflow and I can not run the workflow in batch mode (fails with error code=4).
If I execute the workflow until the loops end, Strings to Documents turns green.
Problem is in the end, that I can not use batch mode to run the workflow.
