I am using KNIME 4.5.2. I am trying to do reading all fixed width files from a directory.
The workflow is:
List Files/Folders → Table Row To Variable Loop Start → Path to String (Variable) → String Manipulation (Variable) (to add file:/ at the beginning or file path) → Fixed Width File Reader
After config the columns, the Fixed Width File Reader can read file content correctly. However, when I try to config the Fixed Width File Reader again, the column configuration is cleared. I have to reconfig the column from the start everytime I want to change it. This problem does not occur if I use the Fixed Width File Reader to read only a single file.
Please guide me how to save the column configuration when using Fixed Width File Reader with variable path.
