I use KNIME 2.4.2 on Win XP and I noticed a possible bug with the Joiner node.
I tried doing an inner join of two input tables based on a common integer column.
The output joined table had more rows (!) than the biggest of the 2 input ones. These rows were duplicates and I had to remove them using an extra GroupBy node (grouping by all columns).
I am pretty sure that this did not happen on previous KNIME versions.
Has anyone else noticed that? Is this fixed on KNIME 2.5?
Thanks in advance,
