Dear community,
I really enjoy the ease of use of the many text processing features in Knime. This is a good step forward towards an allround mining tool kit!
Unfortunately, I came across this issue where I get the same warning "Preprocessing type may not be null!" as soon as I have a Dict Replacer (2 ports) node all set up and ready to run. I have a table creator with two columns (and content) as one input and the table containing the documents as the other. All other consecutive nodes are working fine.
Is this a bug? Or how can I work around this warning?
