"[SOLVED] Wordnet rapidminer extension exception"
I am writing a Wordnet extension for rapidminer which eliminates synonyms. I managed to integrate it in Rapidminer, but I am having a strange exception that says:
WARNING: Caught exception in concurrent execution of Stem Synonyms (Stem Synonyms): java.lang.ClassCastException: com.rapidminer.operator.text.Document cannot be cast to com.rapidminer.operator.text.Document
Can anyone help with this?
