Spec - Columns after execution doesn't update bounds and values

KNIME Analytics Platform

Hi,

When viewing the results after a node execution, specifically at the Spec-columns Tab, there is always the same result (lower-upper bound for numerical columns and occurrencies for categorical columns), even if I execute a Row Filter that filters, for example, a unique nominal value for the column or any node that filters or transforms the data (the only I think it works is Math Expression). Is this a bug?

Thank you

Hello,

 

Column specs are carried with the data unaltered for as long as possible.  This can be useful and is intended behavior. If you want to recalculate a column spec, you will need to use a domain calculator node.  This will generate new column specs according to the parameters defined in the configuration dialog for this node.

 

Cheers,
