Arie Fishler commented on SOLR-1021:
------------------------------------
I'll start from scratch since it might be possible I generated some mess here :)
In FieldStatsInfo I got a NullPointerException in line 51 which indicated that
the nl variable passed to the constructor is probaby null
FieldStatsInfo( NamedList<Object> nl, String fname )
Constructor is only called from QueryResponse.java and I added the if statement
there to avoid the exception (and not call the constructor when this occurs. I
did not get too deep into that but seems like there might be a situation when
the stat info is null for some fields.
I am not sure if this is the best solution or it might indicate another
problem. This solution works for me.

> Affects Versions: 1.4

> Reporter: Arie Fishler
> Priority: Minor
> Attachments: SolrResponse.java

>
> A NullPointerException is thrown at line 51 of class FieldStatsInfo since the

> Seems like this occurs when the search returns with no results but there were
> some setGetFieldStatistics defined for some fields.
