Hi fellas,
I'm a total noob in RapidMiner, I've just installed it on Mac.
My problem is sort of interesting for me. I'd appreciate any help. Here is my process:

In my process when I apply a "replace missing values" operation on a data set and run the process, only the numeric missing values are replaced by their Average value, nominal (binominal and polynominal) missing values are still missing and are not replaced.

However (this is where it gets strange for me) when I point on the output node of the "replace missing values" operator in the diagram (process view) I see that all missing values are replaced.

I'd really want to know if this is a bug or am I doing some ridiculous mistake.
Thanks a lot.
