"OrientDB error occurred during the retrieval of the double value at column 'age'"
I tried using RapidMiner with OrientDB like in http://www.kwoxer.de/2014/11/05/rapidminer-mit-orientdb-jdbc-verbinden-tutorial/ (German)
So I have a Class Person with some entrys in there.
Now I SELECT the name of the Persons. That works great (http://i.imgur.com/IKztCFj.png).
But somehow if I want to select anything else than a String value. I always get this error message.
As an example the Person Class hat the property age, which is an integer: http://i.imgur.com/GH5EwwH.png
Is there anything I can do about this. Why does it work for Strings but not for the other datatypes? Mabye using another Operator or casting the values before?
