Fuseki2 Delete blank node

[Wojciech Ciesielski]

Hi again :)

DELETE DATA

{
  GRAPH <http://przyklad.pl/>
  {
     _:asdfasd
        <http://przyklad.pl/TypObiektu#jest>
                <http://przyklad.pl/TypObiektu#test>      
  }
}

fuseki give me that error:
Error 400: Line 5, column 6: Blank nodes not allowed in DELETE templates: 
_:asdfasd
Fuseki - version 2.0.0 (Build date: 2015-03-08T09:49:20+0000)

It is any way too delete blank node from fuseki using SPARQL?
Or using usnig java ?
I know i can delete it from fuseki manualy.

Thanks
