If I try to send the query I get the following exception: `[2017-10-11T10:43:50,952][ERROR][o.e.b.ElasticsearchUncaughtExceptionHandler] [] fatal error in thread [elasticsearch[UmQ8KQQ][search][T#7]], exiting java.lang.IncompatibleClassChangeError: Found class org.elasticsearch.search.SearchHits, but interface was expected at org.codelibs.elasticsearch.df.content.csv.CsvContent$OnLoadListener.onResponse(CsvContent.java:136)...

+1 from me. Also looking for a widget library for Angular2 / Angular4.
