The extractFacetInfo(...) method of QueryResponse object throws
NullPointerExcpetion when the facetQueries are null.
The code in bold will throw NullPointerException if the fq param is null.
// Parse the queries
_facetQuery = new HashMap<String, Integer>();
NamedList<Integer> fq = (NamedList<Integer>) info.get( "facet_queries"
);
for( Map.Entry<String, Integer> entry : fq ) {
_facetQuery.put( entry.getKey(), entry.getValue() );
}
the patch for this is
// Parse the queries
_facetQuery = new HashMap<String, Integer>();
NamedList<Integer> fq = (NamedList<Integer>) info.get( "facet_queries"
);
if(fq!= null)
{
for( Map.Entry<String, Integer> entry : fq ) {
_facetQuery.put( entry.getKey(), entry.getValue() );
}
}
