Hi,

why not use the WordList to data operator?

Hi,

thats an error with meta data propagation. you can still type the attribute name and it will work.

the steps after that one do no work... ok till nominal to binominal, but then no frequent itemsets found... only single words

Is there any way to fix this error with metadata propagation to avoid getting this 'potential problem detected' warning?

Hi,

theoretically you can use Set Meta Data to define the meta data manually. But thats not convenient. We can just not know what words and thus columns will appear, so there is no way to do this automatically.

Best,

Martin
