I have built custom builtin gtbuiltinint:DTT2, and for giving (xsd:double) ?r it can correctly return (xsd:int) ?rr with the save value of ?r. but when run the fllowing SQWRL statment, the exception:Exception in thread "main" org.swrlapi.sqwrl.exceptions.SQWRLException: error creating SQWRL query: expecting xsd:int argument for slicing operator sqwrl:nth is thrown.
I was confused that sqwrl:nth(1) can run correctly while sqwrl:nth(?rr) can not.
I am going to crazy.... please help!!!
