Hi. The output of this operator when pre-processing text, is an example set with a number of special and regular attributes. When I try to apply other operators to this output at a later stage, RapidMiner seems to ignore all the regular attributes whilst keeping special attribute (text) i.e. the data table has only one attribute (text) and the regular attributes are ignored. In the first printout, one can see that regular attributes are ignored. On the second printout, looking at the results output, I can see the regular attributes - in fact it states there are 2906 regular attributes.
Why is this and how can I ensure that the attributes are kept in the table for processing at a later stage?
