[basex-talk] Iter.get() giving null

Hi, I am trying to execute a query in java and trying to fetch the result set using Iter Object. But Iterating through the result set return "null", but when i am executing the same query and getting Result object i am able to see the result set. Why this is happen. Please Help Me. QueryProcessor pr = new QueryProcessor("let $a := /data/product/* return $a ",context); pr.context(dataset); Now I am taking Iter object as: Iter itr=pr.iter(); Now, executing itr.get(0) gives me "null", but when i execute it as Result rs = pr.execute() Sytem.out.println("Products ::" + rs) ... it shows the fetch products. But, also itr.next().serialise() also gives me the result.
