[bug or feature ?] Row Filter - Specs remain of original, not filtered range

[s.roughley]

The column domain (which is what you are referring to) isn’t recalcualted on every node - I assume because it takes time/processor power/memory to do. Most of the time that’s not much of an issue but for filters/splitters it is annoying. You can force the recalculation using the Domain Calculator node:

Domain Calculator

Incidentally, if you find the default 60 values for String column domains frustrating then there is a fix here:

Nominal Value Row Filter - Issue on limitation of values

You can also change the default from 60 to some other value by adding the following line to the knime.ini file: -Dknime.domain.valuecount=1000 (where 1000 is whatever value you think is big enough to cover your needs and not so big as to gobble up all the available memory during node execution, as the nominal values are stored in memory as the output table is generated) Steve
