No attributes to filter on (Filter Examples)
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.
