[Wikidata-tech] wikidata toolkit - property filter

Hello All

Property filter does not seem to be working for me.

My code:

WikibaseDataFetcher wbdf = WikibaseDataFetcher.getWikidataDataFetcher();

wbdf.getFilter().setPropertyFilter(Collections.singleton(this.dataObjectFactory.getPropertyIdValue("P57", "http://www.wikidata.org/entity")));

wbdf.getFilter().setPropertyFilter(Collections.singleton(PropertyIdValueImpl.create("P57", "http://www.wikidata.org/entity")));

i am still receiving all statements. what am i missing ?

Thanks in advance Assaf
