Description

When doing a search like

http://localhost:8983/solr/select?group=true&group.func=product(fildname1,fieldname2)&group.facet=true&facet=true&facet.field=fieldname3

an error is returned in response where facets are normally returned:

java.lang.ArrayIndexOutOfBoundsException: 0 at org.apache.solr.request.SimpleFacets.getGroupedCounts(SimpleFacets.java:358) ...

The function used can be any function, not product only. There is no such error if group.facet is omitted or group.field is used instead of group.func. It seems that group.field parameter is expected to be defined when calculating grouped facets.
