1. Create a guided dtable. 2. Add condition column restricting an int field - choose '>' operator and set the (optional) value list to '1,2,3'. 3. Add an action column. 4. Add two rows. 5. Fill in the same values for both rows. There should now be a warning about redundant rows - no such thing is present. If you change the int value in one row, you'd expect a subsumption warning, this also does not appear. If you change the rows to be the same again and change the operator for the cond. column to '==', the expected redundancy warning is also missing, but it appears if you switch the int values in both rows.
