Subject: NullPointerException while sorting on INT
Hi friends,
I am getting NullPointerException while sorting on a field using
SortField.INT
same is working for SortField.STRING
Code Snippet:
SortField sortfield = new
SortField("CURRENT_BID",SortField.INT,false); // asceding sort on current
bid value
Sort sort = new Sort();
sort.setSort(sortfield);
hits = msearcher.search(bqmain,sort); // this statement
generates NullPointerException
Stack Trace:
java.lang.NullPointerException
at
org.apache.lucene.search.MultiSearcherThread.hits(ParallelMultiSearcher.java:286)
at
org.apache.lucene.search.ParallelMultiSearcher.search(ParallelMultiSearcher.java:141)

at _auctionSearcher__jsp._jspService(_auctionSearcher__jsp.java:359)
Same is working if i change "SoftField.INT" to "SortField.STRING"....
In index the field "CURRENT_BID" has no null value in any document....
I am using lucene 2.1.
Thanks.
