public QueryIterator exec(Binding binding, PropFuncArg argSubject, Node predicate,
PropFuncArg argObject, ExecutionContext context) {
argObject = Substitute.substitute(argObject, binding);
argSubject = Substitute.substitute(argSubject, binding);
ExprList subjectExprList = argSubject.asExprList(); <-- PropFuncArg cannot be empty
ExprList objectExprList = argObject.asExprList(); <-- PropFuncArg cannot be empty
I can run my app standalone in Eclipse and allow it to continue with errors but maybe this can be fixed?
