SOLR : ArrayIndexOutOfBoundsException from SolrDispatchFilter

[Rohit Kumar]

Need help to figure out the error below.


*Code Snippet*:

public class ConnectionComponent extends SearchComponent {

@Override

public void process(ResponseBuilder rb) throws IOException {

    NamedList nList = new SimpleOrderedMap();



    NamedList nl= new SimpleOrderedMap();


    List<Document> ld = new ArrayList<Document>();
    Document mydoc = new Document();
    mydoc.add(f); //IndexableField f not null
    ld.add(mydoc);

    nl.add(someKey, ld);

    nList.add(otherKey, nl);



    // rb instance of ResponseBuilder

    rb.rsp.add(returnKey, nList);

  }

}
