I’m now using knime V4.0 however I meet a problem when using the new node “string to number” inside a loop (where some file have some numbers and others don’t).
It’s perfectly working with the old “deprecated string to number” node. Is it a bug of the new version? or is there another more simple way to do it?
With the enforce exclusion inclusion list you can define what happens to new columns.
If you for example use as here enforce inclusion, with an empty list, all columns will always be excluded.
If you change this to an empty exclusion list, all columns will always be included.
