I have a problem with using Filter Examples. I am using data that is already in Rapidminer ("Repository/Samples/data/Iris").  After putting data in the process I put the Filter Examples and connect them. Then in the parameters, I press "Add Filters" but in the left box, there are no attributes shown.  I don't know, how to getting metadata from different data set. sometimes, I select Iris data set and select "synchronize metadata with real data" the problem was solved. but, when I changed the dataset from Iris to Titanic  There was the same problem.

    Hi,
    did you maybe deactivate the auto meta data propagation? This is the "Validate Automatically" option under process.
